Giant folliculosebaceous cystic hamartoma

We report a case of a giant cystic cutaneous adnexal hamartoma which showed fibrofollicular units embedded in the stroma with aberrant fat tissue. There were many sebaceous lobules in the fibrofollicular units, and its histologic features were consistent with conventional folliculosebaceous cystic hamartoma. Given the unique clinical history and appearance, this lesion is considered to be a congenital variant.

Pulmonary Chondroid Hamartoma Presenting as an Inflatable Neck Mass: Case Report and Clinicopathologic Analysis

Pulmonary hamartomas most often present as solitary coin lesions of the lung. Less frequently, they can present as cystic lesions in the pulmonary parenchyma. We describe a case of a cystic pulmonary hamartoma presenting as an inflatable neck mass. The lesion was successfully treated by surgical excision using a stated transcervical and thoracotomy approach. The differential diagnosis of inflatable cervical masses is outlined along with a discussion of the pathogenesis and treatment of hamartomas. A clinical technique that is helpful in localizing the source of inflatable cervical masses is described for use when radiologic examinations are not specific in locating the source of the lesion.

Folliculosebaceous Cystic Hamartoma Associated with Rosacea

A case of folliculosebaceous cystic hamartoma associated with rosacea is presented. Clinically, a solid, 5-mm-sized nodule was observed on the nose which showed telangiectasia and a waxy appearance. Histologically, a large horn cyst was located in the dermis, and was continuous with the surface epidermis. It was associated with mature sebaceous glands and immature hair follicles. Folliculosebaceous cystic hamartoma and similar cases have recently been reported, but this is the first report accompanied by rosacea.

Folliculosebaceous Cystic Hamartoma

The clinical and histological features of a recently recognized entity, folliculosebaceous cystic hamartoma, are reported. The peculiarity of our case is a previously unreported neural proliferation in the stroma.

Mesenchymal Cystic Hamartoma of the Lung

We report the case of an asymptomatic 51-year-old man, presenting with chest X-ray abnormalities consisting in multiple pulmonary nodules; the diagnosis of mesenchymal cystic hamartoma of the lung was made by an open lung biopsy, revealing both nodules of mesenchymal cells and cysts with a lining of normal or metaplastic epithelium. Clinical and pathological characteristics of this rare entity are reviewed.

Endorectal sonography in the evaluation of rectal and perirectal disease.

Endorectal sonography initially was developed for evaluation of the prostate and now has been adapted for evaluation of rectal and perirectal disease. We used endorectal sonography to evaluate a spectrum of diseases, including primary and recurrent rectal carcinoma, metastases, villous adenoma, leiomyosarcoma, endometriosis, sacrococcygeal teratoma, chordoma, retroperitoneal cystic hamartoma, pelvic lipomatosis, diverticulitis, and perirectal abscess. The technique has been useful in localization of perirectal abscesses and in sonographically guided biopsy of perirectal masses. Knowledge of normal sonographic anatomy of the rectum is essential in the evaluation of rectal and perirectal disease. In this essay, we describe the technique of endorectal sonography and illustrate the sonographic findings in a variety of diseases.

Folliculosebaceous Cystic Hamartoma

Five examples of a distinctive sebaceous malformation, designated "folliculosebaceous cystic hamartoma," form the basis of this study. Criteria are proposed for specific diagnosis of this hamartoma and for differentiation of it from sebaceous gland hyperplasia, steatocystoma, dermoid cyst of skin, and sebaceous trichofolliculoma.

Cystic pulmonary hamartoma

A case of cystic pulmonary hamartoma is reported and the literature is reviewed. According to the literature, only 6 well-documented cases have been previously reported, and all the patients including our patient fared well after operation.

Retrorectal cystic hamartoma diagnosed by fine‐needle aspiration biopsy

A 17-yr-old postpartum female presented with a large multicystic mass posterior to the rectum, thought clinically to be an abscess. Fine-needle aspiration biopsy revealed numerous squamous cells. The diagnosis of retrorectal cystic hamartoma was considered and subsequently confirmed by the surgical resection specimen. The cytologic and histologic findings are presented along with a discussion of the entity "retrorectal cystic hamartoma," including a differential diagnosis of presacrococcygeal cysts.

Multilocular cystic nephroma: Report of three cases

Multilocular cystic nephroma is an uncommon renal neoplasm which in childhood usually presents as an abdominal mass. The same condition is also described as multilocular kidney and multilocular cystic hamartoma. The clinical presentation, and radiological findings in three cases of multilocular cystic nephroma are described.

A giant cystic mesenchymal hamartoma of the liver: Diagnosis, management, and study of cyst fluid

A 21-yr-old West Indian woman with a giant hepatic cyst is reported. Preoperative investigations revealed that it was not a simple congenital cyst but that it was highly vascular. Studies of the cyst fluid obtained by percutaneous catheter drainage suggested that the epithelial lining was of bile duct origin. Fluid output was increased by secretin administration, but remained unchanged after amiloride. Bromsulphthalein did not enter the cyst fluid after intravenous injection. A hemihepatectomy was performed and the histologic appearances of the lesion were consistent with cystic mesenchymal hamartoma, a rare lesion in this age group. The patient is well 4.5 yr later.

An encephalocele of the sphenomaxillary type: Case report

A report is presented of a cystic malformation with elements of an encephalocele and a cystic hamartoma of the nasopharynx in a girl aged 9. The pathogenic origin was probably that of a spheno-maxillary type of basal encephalocele which in most classifications is listed as a theoretical type. The surgical approach for enucleation, by hemimaxillotomy and splitting of the soft palate is described.

Hepatic tumors, surgical treatment and its results

During the period from March 1954 to June 1976, 489 cases of hepatic tumors were experienced at the Department of Surgery, National Taiwan University Hospital. The pathological classification are: Hemangioma 5; Cystic hamartoma 2; Hemangioendothelioma 2; Non-parasitic localized cyst 5; Polycystic liver 9; Tuberculoma 1; Actinomycosis 1; Hyperplasia 1; Adenoma 1; Primary liver sarcoma 2; Primary liver cancer 442; and Metastatic liver cancer 18. Of the 489 hepatic tumors, two cases were treated with excision, 148 cases with hepatic lobectomy and nine cases of polycystic liver were treated with fenestration. Benign hepatic tumors are all well up to eight years after the operation, 14 cases of primary liver cancer survived five to 17 years after hepatic lobectomy.

Cystic Hamartoma of the Liver in a Pediatric Patient

A case of cystic mesenchymal hamartoma in a 2-year-old boy is presented. The overall angiographic appearance closely resembled that of the more common renal angiomyolipoma, with the addition of multiple focal avascular areas representing the cystic component of the lesion. The coexistence of these angiographic findings in a young patient with an otherwise asymptomatic upper abdominal mass should suggest cystic mesenchymal hamartoma.

Cystic Hamartoma of the Left Hepatic Bile Duct

A 35-year-old woman had intermittent obstructive jaundice due to a suspected ball-valve type mechanism at the porta hepatis, which was confirmed by endoscopic retrograde pancreatic cholangiogram. At reexploration, a benign cystic hamartoma of the left extrahepatic bile duct was found and removed, with no recurrence of symptoms. Pathogenesis of jaundice in unilateral extrahepatic bile duct obstruction remains obscure. (<i>JAMA</i>235:630-631, 1976)

Congenital cystic adenomatoid pulmonary hamartoma in a newborn infant.

Case report of a newborn infant with acute respiratory distress. Roentgenologic signs of patches of increased density with scattered round and oval areas of radiolucency suggested the diagnosis of congenital cystic adenomatoid pulmonary hamartoma. Diaphragmatic hernia had to be excluded by a gastrografin®-meal gastrointestinal series. During surgery a right lower lobectomy was done. The diagnosis was proved by gross and microscopic examinations of the affected parenchyma of the lung.
