Subcutaneous Hydatid Cyst Research Articles

Case Report: An exceptional localisation in the thigh of a giant primary subcutaneous hydatid cyst.

Hydatid disease is a zoonotic disease caused by the larval stage of Echinococcus granulosus and is found globally. Although the liver and lungs are the most prevalent sites of involvement, sub-cutaneous hydatid cysts are rare especially in the primary occurrence. Sub-cutaneous hydatid cysts usually are noticed as slow growing, painless, and mobile masses beneath the overlying skin which is usually normal and are generally found on the trunk and proximal extremities. To the best of our knowledge, very few cases of primary subcutaneous hydatid cysts of the thigh have been documented. We present a case of a 30-year-old woman from a rural setting, who has a large, painless swelling on her thigh. Imaging studies confirmed the presence of a primary subcutaneous hydatid cyst, which is an atypical presentation of the disease. The entire lesion was excised surgically without any evidence of recurrence for a long period postoperatively. This case illustrates the difficulty in establishing a diagnosis and the importance of early surgical management in these cases.

Hydatid cyst of the postero-internal side of right leg: A case report

The primitive and isolated subcutaneous localization of the hydatid cyst is exceptional, even in countries where hydatid disease is endemic. We report the case of a young patient with a subcutaneous hydatid cyst without associated visceral damage.

Solitary primary subcutaneous hydatid cyst of the buttock – Case report and literature review

Hydatidosis is an endemic parasitic disease affecting in most cases the parenchymal organs. The involvement of the soft tissue is a rare pathology that, left untreated, can lead to rupture and potentially catastrophic anaphylaxis. In this article, we describe the case of a 42-year-old male who developed a subcutaneous hydatid cyst in the buttock as a solitary primary localization. Consequently, the patient underwent a successful surgical excision with uneventful post-operative recovery.

Subcutaneous Hydatid Cyst in Laboratory Mice: Is it a Suitable Method for Evaluating Therapeutic Agents against Hydatid Cyst?

Hydatid disease is an economic and public health concern in many countries. Currently, surgery is the main treatment option for hydatid disease. In the surgical treatment of hydatidosis, the use of scolicidal agents is very important due to inactivating live protoscoleces and preventing the recurrence of infection. Therefore, it is necessary to investigate newscolicidal agents and novel medications with higher safety and efficacy. In the previous in vitro studies, the scolicidal effects of the methanolic extracts and aromatic water of Zataria multiflora (Z. multiflora) have been demonstrated. Consequently, in this study, the impact of the nanoemulsion of Z. multiflora essential oil on subcutaneous hydatid cysts was compared with albendazole (ABZ). Fifty laboratory male mice were inoculated with 300 viable protoscoleces subcutaneously on the two sides of the abdomen. Following five months of infection, the remaining infected mice (n=42) were allocated into two treatment and one control (without treatment) groups containing fourteen animals each. Group A received ABZ at the dose of 50 mg/kg for 60 days, group B received the nanoemulsions of Z. multiflora at the dose of 50 mg/kg in drinking water for 60 days, and group C was considered as the control group. All the infected mice were euthanized and necropsied two months post-intervention. Afterwards, the cysts were cautiously collected and their number, size, and weight were compared between the mice of different groups. The mean number of hydatid cysts indicated that the nanoemulsion of Z. multiflora essence had a relative superiority to ABZ. On the other hand, the therapeutic effect of ABZ was higher than the nanoemulsion of Z. multiflora essential oil in terms of the mean weight and mean size of hydatid cysts. However, no significant difference was observed between the groups (P>0.5). Overall, the number, weight, and size of cysts were not significantly different between the groups in this investigation. The lack of satisfactory therapeutic results in this study might be due to the location of hydatid cysts in the subcutaneous space.

Primary Subcutaneous Hydatid Cyst of the Face: A Rare Entity with Emphasis on Radiological Evaluation

: Despite being an extremely common disease worldwide, especially in the temperate areas, hydatid disease continues to startle by varying presentations. The current study presented a case of primary hydatid in the subcutaneous region of face of a young patient accurately diagnosed preoperatively by the characteristic of imaging findings on ultrasonography (USG) and comouted tomography (CT) and confirmed on surgery. Although it was a rare site of presentation, the radiological features were essentially the same as elsewhere in the body and could help to make correct decision to manage the patient.

Subcutaneous hydatid cyst in forearm – a diagnostic dilemma with neurofibroma

Hydatid disease caused by larval stage of Echinococcus granulosus usually affects lungs and liver of human and animals. Affection of subcutaneous tissue is rare; though not rarest but often clinically mistaken as neurofibroma or lipoma. Preoperative diagnosis is mandatory to avoid surgical contamination or future accidents. Two middle aged males presented with forearm nodules and one female presented with an arm nodule; all of which on needle aspiration cytology and wet smear examination provisionally diagnosed as hydatid cyst, later confirmed radiologically and surgically. Primary hydatid disease constitutes potentially serious differential diagnoses in subcutaneous swelling.Bangladesh Journal of Medical Science Vol.15(4) 2016 p.634-636

A solitary primary subcutaneous hydatid cyst in the thigh: a case report

Hydatid disease is a parasitic infestation caused by Echinococcusgranulosus. It occurs frequently in liver and lung. Hydatid disease of the soft tissue is uncommon. In this paper, we report a case of a primary subcutaneous hydatid cyst in the thigh. We report a case of a 45-year-old female who presented to our hospital with a painless subcutaneous mass in the medial aspect of the right thigh for one year. Computed tomography scan demonstrated a subcutaneous cystic lesion close to adductor magnus muscle. The diagnosis of hydatid cyst was suspected peroperatively, complete surgical excision of the mass was done and the patient had an uneventful post-operative recovery. The suspected diagnosis was confirmed by histopathological examination. This case shows that hydatid cyst should be considered in the differential diagnosis of any cystic mass at different anatomical sites, especially in endemic regions. Total excision of the cyst with an intact wall remains the mainstay of treatment.

An unexpected etiology of a subcutaneous mass: hydatid cyst.

Hydatid disease is a parasitic infestation that is caused by the cestode Echinococcus granulosus (E. granulosus) that has a higher prevalence in South American, Mediterranean, Middle Eastern, and East Asian countries. Humans are incidental intermediate hosts because of the ingestion of embryonated eggs in food contaminated with dog feces. In humans, the liver and the lungs are the most commonly affected sites of the body; the other sites include the peritoneum, spleen, kidney, uterus, and pancreas [[1]]. A solitary subcutaneous hydatid cyst is extremely rare. In a different series, the frequency of subcutaneous tissue involvement was approximately 2%; however, primary lesions without secondary damage to any organs have been very rarely reported [[2]]. We herein present an unexpected and uncommon etiology of a subcutaneous cyst diagnosed as a hydatid cyst, which might be of interest to surgeons.

Primary Subcutaneous Hydatid Cyst Presenting With Low Back Pain

Primary Subcutaneous Hydatid Cyst Presenting With Low Back Pain

English

In a tropical country like India, it is not rare to see patients with parasitic cysts. Hydatid cysts most often caused by the parasite Ecchinococcus granulosus present as space occupying lesions of the lung or liver. Isolated musculoskeletal and subcutaneous Hydatid cysts in the absence of any involvement of the lungs and liver are very rare and only a handful of cases have been reported in literature. We report an interesting case of an isolated subcutaneous Hydatid cyst of the gluteal region presenting as a gluteal abscess in a 45 year old lady. This report aims to highlight the unique presentation of the spectrum of Hydatid disease.

Left Lumbar Subcutenous Hydatid Cyst Disease: A Case Report

Hydatid cyst disease is endemic in our country. This disease is most commonly detected in the liver and lung, but it can be detected rarely in the soft tissue, muscles and subdermally. In this study, we mentioned a case with subcutaneous hydatid cyst disease without any primary lesion. In this case, a left lumbar subdermal cyst was totally excised and the germinative membrane of the cyst was detected and sent for pathological examination and study resultsreported hydatid cyst disease. The patient was followed up for one year with laboratory and radiological studies. No recurrent hydatid cyst was observed. Turkey is an endemic area for hydatid cyst disease and we should bear this disease in mind as a differential diagnosis in all cystic lesions.

Primary subcutaneous implantation hydatid cyst

A 70-year-old female patient presented with subcutaneous cystic swelling following cholecystectomy. The patient underwent surgery and was eventually diagnosed as having hydatid cyst (HC). Primary subcutaneous HC is rare, but primary implantation HC is unknown. This report is an index case of such an entity.

Primary Subcutaneous Cyst Hydatid: Presentation of Two Cases

Subcutaneous localization of an hydatid cyst is quite rare, and is found in literature in the form of case presentations. Other points worthy of attention are the lack of other foci in the majority of these cases, and the negative results of serology. In this study, two primary subcutaneous hydatid cyst cases, one in the facial area (53-year old female) and the other on the back (37-year old female), have been examined with reference to literature. In both cases, no other foci were determined, and the hydatid cyst serology was negative. When these two cases and the cases in literature are studied, it can be said that the hydatid cyst grows faster than previously known. It is noteworthy that, generally, in atypically localized cyst hydatids, there are no other foci (liver and lungs) and the serology is negative. This shows that the etiopathogenesis of the disease is not fully understood as yet.

Hydatid Cyst of Paravertebral Muscle Mimicking Disc Herniation

Case report. To present a case of primary hydatid cyst in the lumbar subcutaneous tissue affecting posterior paravertebral muscle and mimicking disc herniation. Cystic hydatid disease is a rare but significant parasitic disease in endemic areas. Musculoskeletal or soft tissue hydatidosis accounts for about 0.5% to 5% of all echinococcal infections in endemic areas and is almost secondary to the hepatic or pulmonary disease. Primary lumbar subcutaneous hydatid cyst affecting paravertebral muscle and extending to neural foramina is a very rare condition even in endemic areas. A 25-year-old-female patient was admitted with swelling and pain in the right lumbar region for 3 months. The pain was reflecting in the right gluteal region and the right leg. Lumbar extension and right lateral flexion was painful and straight leg raising test was positive at right side. There was a mild hypoesthesia at L5 dermatome. According to the magnetic resonance image that the clinician obtained for initial diagnosis of lumbar disc herniation, we found multi-cystic masses located at the right paravertebral muscle at the level of L3-L5 which extended to L4-L5 neural foramina and at subcutaneous tissue at the right gluteal region. The patient was operated for the purpose of removal of cysts. Postoperatively, diagnosis of hydatid cyst was confirmed by histopathology. By this case, we emphasize that cystic hydatid disease should be taken into consideration in the differential diagnosis of low back pain and could mimic disc herniation. N/A.

Primary Subcutaneous Hydatid Cyst with Palisading Granulomatous Reaction

Palisading granulomatous reactions are prominent microscopic characteristics that are seen in many diseases. Isolated subcutaneous cystic echinococcosis is rarely documented. Palisading granuloma as a host immune reaction to Echinococcus granulosus in an isolated primary subcutaneous hydatid cyst has been reported only once before. In this report, we are describing a 53-year-old male who developed a slowly growing subcutaneous thigh mass. Light microscopy confirmed the presence of hydatid cyst. Further radiological workup for liver and lung has not shown any visceral hydatid focus.

Primary subcutaneous hydatid cyst in the left distal thigh.

Human cystic echinococcosis, a zoonotic infection caused by Echinococcus granulosus, remains a largely extended public health problem in endemic regions. Hydatid cyst disease can occur in all viscera and soft tissues, although the liver and the lungs are the most commonly involved organs. Primary hydatid disease of the soft tissue is extremely rare, even in endemic areas, and accounts for 0.5-5.4% of all hydatid disease cases, with very little data on the incidence of subcutaneous echinococcosis. The paper will be focused on analyzing this extremely rare disease. A 14-year-old girl came to our Department of pediatric Surgery with a painless, round, palpable mass in the subcutaneous tissue of the distal anteromedial side of the left thigh. Based on clinical and laboratory findings and imaging techniques, we suspected a hydatid cyst. She was treated successfully with complete cyst excision. The macroscopic appearance suggested a hydatid cyst. Histopathologic examination of the specimen revealed a hydatid cyst. No other organ involvement has been detected. Hydatid disease should be considered in the differential diagnosis of all cystic masses in all anatomic locations, especially in regions where the disease is endemic.

A solitary primary subcutaneous hydatid cyst in the abdominal wall of a 70-year-old woman: a case report

IntroductionA solitary primary hydatid cyst in the subcutaneous abdominal wall is an exceptional entity, even in countries where the Echinococcus infestation is endemic.Case presentationWe report a case of a 70-year-old Caucasian woman who presented to our hospital with a subcutaneous mass in the para-umbilical area with a non-specific clinical presentation. The diagnosis of subcutaneous hydatid cyst was suspected on the basis of radiological findings. A complete surgical resection of the mass was performed and the patient had an uneventful post-operative recovery. The histopathology confirmed the suspected diagnosis.ConclusionHydatid cyst should be considered in the differential diagnosis of every subcutaneous cystic mass, especially in regions where the disease is endemic. The best treatment is the total excision of the cyst with an intact wall.

Primary hydatid cyst in the soft tissue of the face: An exceptional occurrence

To emphasize that solitary hydatid cyst can be localized in the soft tissue and present as a soft tissue mass even in an unusual site like face, we report the case of a 42-year-old male patient presenting with a slowly growing mass in right temporal region. Computed tomography (CT) scan showed an encapsulated mass with multiple cysts. Histopathological examination revealed the characteristic findings, which were consistent with soft-tissue hydatid disease. In the absence of visceral organ involvement, this is the first reported case of a primary subcutaneous hydatid cyst in the skin of face in India. In the English literature, only one case of this kind has been reported till date. When imaging methods confirm cystic nature of a swelling, even in unusual sites, one should always keep a possibility of hydatid cyst and manage accordingly during surgery to avoid precipitation of acute anaphylaxis.
