Sarcoid Granulomas and Systemic Sarcoidosis Triggered by Cosmetic Tattoos.

Morpheaform sarcoidosis: A case presentation of an uncommon cutaneous manifestation of sarcoidosis

To explore the clinical characteristics and systemic manifestations of sarcoidosis with ocular involvement. The clinical data of 19 cases of sarcoidosis with ocular involvement confirmed by pathology at Beijing Tongren Hospital from March 2004 to February 2014 were analyzed retrospectively. The ocular manifestations, chest imaging findings, laboratory tests and pathological diagnosis were reviewed. And the clinical features of sarcoidosis with ocular involvement were summarized. Among them, there were 6 males and 13 females with an average age of (47 ± 14) (16-76) years. The ocular symptoms were the initial presenting manifestations of sarcoidosis in 12 cases while 2 cases presented ocular symptoms during the course of disease. And aother 5 cases without ocular symptoms were confirmed to have ocular involvement by eye examination. The main manifestations of ocular sarcoidosis were uveitis (n = 16), chorioretinitis (n = 3), retinal vasculitis (n = 2), optic neuritis (n = 1) and orbital mass (n = 3). The key feature of sarcoidosis was bilateral hilar lymphadenopathy (BHL) (14/16) on chest film. The diagnosis in 17 cases was confirmed by biopsy of extra-ocular organs. The positive diagnostic rate of bronchial biopsy was 8/9. Ocular involvement in sarcoidosis is relatively common due to a variety of ocular manifestations and serious vision impairment in some patients. Ophthalmologic examination is essential in the clinical management of sarcoidosis. Chest imaging and bronchial biopsy are important for the diagnosis of sarcoidosis with initial ocular manifestations.

Sarcoidosis is a multisystem granulomatous disease associated with the expansion and activation of CD4+ T-lymphocytes and macrophages. To investigate the immunopathology of active and nonactive pulmonary sarcoidosis, we have examined the expression of cytokine gene transcripts in bronchoalveolar lavage cells from 15 patients with active pulmonary sarcoidosis, eight patients with non-active pulmonary sarcoidosis, and nine normal controls. Using in situ hybridization, the percentage of cells expressing messenger ribonucleic acid (mRNA) for interleukin (IL)-1 beta, IL-2, IL-3, IL-4, IL-5, IL-6, IL-10, IL-12 and interferon-gamma (IFN-gamma) were compared in the groups studied. In individuals with active sarcoidosis, there were significantly greater proportions of cells expressing mRNA for IL-2, IL-10, IL-12 and IFN-gamma than in subjects with nonactive disease and normal controls (p < 0.01). There was no significant difference in the percentage of positive cells expressing IL-10 and IL-12 mRNA in the nonactive group compared to the normal controls (p > 0.05). No significant differences in the percentages of IL-3, IL-4 and IL-5 mRNA positive cells were observed between active and nonactive sarcoidosis patients and normal controls (p > 0.05). These results demonstrate that there is a preferential expression of T-helper type 1 cytokines in pulmonary sarcoidosis, and that cytokines related to macrophage activation are the most prominent. In addition, these data implicate an elevated expression of interleukin-2, -10 and -12 and interferon-gamma in active compared to nonactive sarcoidosis.

The development of granulomatous lesions within tattoos is a well-recognized occurrence in individuals with sarcoidosis. The characteristic histopathological finding of sarcoidosis is the presence of noncaseating granulomas; however, similar histopathogical findings may be seen in foreign body granulomas. Several reports have challenged the assertion that the presence of foreign material within sarcoidal granulomas is incompatible with a diagnosis of sarcoidosis. We describe a patient who had multiple linearly arranged papules along her eyebrows and the vermillion border of her upper lip. She had had cosmetic tattooing performed on these areas 3 year prior to presentation. Histopathologic examination revealed sarcoidal granulomas, polarizable foreign material, and pigment granules. Hilar adenopathy was noted on a chest radiograph. After 4 months of treatment with a midpotency topical steroid and doxycycline, she experienced complete clearance of her cutaneous lesions and normalization of chest x-ray film findings. This case demonstrates a unique adverse result after cosmetic tattooing and highlights the concept that granulomatous histopathologic findings containing foreign material should not be an exclusionary criterion for the diagnosis of sarcoidosis. In this setting, further investigation for the presence of systemic disease is indicated.

Background: Sarcoidosis is a chronic granulomatous inflammatory disease of unknown etiology often involving the lungs and intrathoracic lymph nodes. The natural course of sarcoidosis is variable from spontaneous remission to significant morbidity or death. But, the mechanisms causing the variable clinical outcomes or any single parameter to predict the prognosis was not known. In sarcoidosis, the number and the activity of CD4 + lymphocytes are significantly increased at the loci of disease and their oligoclonality suggests that the CD4 + lymphocytes hyperreactivity may be caused by persistent antigenic stimulus. Recently, it has been known that CD4+ lymphocytes can be subdivided into 2 distinct population(Th1 and Th2) defined by the spectrum of cytokines produced by these cells. Th1 cells promote cellular immunity associated with delayed type hypersensitivity reactions by generating IL-2 and IFN-. Th2 cells playa role in allergic responses and immediate hypersensitivity reactions by secreting IL-4, IL-5, and IL-10. CD4+ lymphocytes in pulmonary sarcoidosis were reported to be mainly Th1 cells. IL-12 has been known to play an important role in differentiation of undifferentiated naive T cells to Th1 cells. And, Moller et al. observed increased IL-12 in bronchoalveolar lavage fluid(BALF) in patients with sarcoidosis. So it is possible that the elevated level of IL-12 is necessary for the continuous progression of the disease in active sarcoidosis. This study was performed to test the assumption that IL-12 can be a marker of active pulmonary sarcoidosis. Methods: We measured the concentration of IL-12 in BALF and in conditioned medium of alveolar macrophage(AM) using ELISA(enzyme-linked immunosorbent assay) method in 26 patients with pulmonary sarcoidosis(10 males, 16 females, mean age: years) and 11 normal control. Clinically, 14 patients had active sarcoidosis and 12 patients had inactive. Results: Total cells counts, percentage and number of lymhocytes, number of AM and CD4/CD8 lymphocyte ratio in BALF were significantly higher in patients with sarcoidosis than in control group. But none of these parameters could differentiate active sarcoidosis from inactive disease. The concentration of IL-12 in BALF was significantly increased in sarcoidosis patients ( pg/ml) than in normal control ( pg/ml) (p pg/ml) than in inactive disease ( pg/ml) (p=0.001). Also, the concentration of IL-12 in BALF showed significant correlation with the percentage of AM(p pg/ml) than those of control ( pg/ml) (p

Different lymphocyte subpopulations have been evaluated in bronchoalveolar fluid and blood obtained from six patients with active and six with inactive pulmonary sarcoidosis and from six normal subjects by means of two recently described monoclonal antibodies, 5/9 and MLR4. The percentages of OKT4 positive (helper) and OKT8 positive (suppressor) T cells were also determined. Patients with active sarcoidosis had significantly higher proportions of 5/9 positive T cells in the bronchoalveolar fluid than patients with inactive disease (p less than 0.01) or normal subjects (p less than 0.001). In contrast, the proportions of 5/9 positive blood T cells were similar in the three groups studied. Patients with active sarcoidosis had also a greater proportion proportion of MLR4 positive T lymphocytes in bronchoalveolar fluid than patients with inactive disease or normal subjects (p less than 0.01 for each comparison), but similar proportions of MLR4 positive blood T cells were found in each group. The ratio of 5/9 positive to MLR4 positive T cells was higher in the bronchoalveolar fluid (but not in the blood) in patients with either active or inactive sarcoidosis than in normal subjects. These observations suggest that the MLR4 negative fraction rather than the MLR4 positive fraction of the 5/9 positive T cells is preferentially expanded in the lungs of patients with pulmonary sarcoidosis and may indicate a secondary role for the MLR4 positive T cells in producing lung injury in this disorder. Comparisons of the OKT4 positive and 5/9 positive T cells showed that in patients with active disease most of the lung T lymphocytes expressed both the OKT4 and the 5/9 surface antigens, so the 5/9 monoclonal antibody may be considered a good marker of activity in this disorder. Pulmonary sarcoidosis may be characterised by the preferential expansion of helper T cell subsets at sites of disease activity.

Cosmetic tattoos may cause burning sensation during magnetic resonance imaging (MRI) and interrupt the procedure, and thereby any diagnostic workup. Tattoos also may cause disturbing artefacts in MRI images. The sensation, which can be painful, is due to magnetic elements in the tattoo ink deposited in the tattooed skin. It is not a thermal burn but a subjective sensation of burning. Tattoo ink bottles can be tested for magnetic properties by the artist in the studio, before cosmetic tattooing is performed, using a simple magnet test. This test and the pitfalls of the test are described. Hospital departments and clinics should be aware of the problem, and patients assessed prior to MRI regarding their tattoos, particularly eyebrows and eyeliners made in brown and dark colors. Red tattoos exemplified by tattooed lips are not prone to MRI-induced burning sensation. The problem is related to inorganic pigments with ferromagnetic properties.

Sarcoidosis is considered a T-helper (Th) 1 related disease, but a transition from Th1 to Th2 pathway activation has been postulated in sarcoidosis-associated pulmonary fibrosis (SAPF). Fraction of exhaled nitric oxide (FENO) is a marker of Th2 airway inflammation, but alveolar concentration of nitric oxide (CANO) can be measured to assess Th2 inflammation in the periphery of the lung. The aim of this study is to assess whether CANO can be considered a biomarker of SAPF or active pulmonary sarcoidosis. In this single-center retrospective study, we compared exhaled NO levels of patients with pulmonary sarcoidosis without fibrosis (N= 11) with those obtained from patients with SAPF (N= 15). Clinical data, as well as respiratory function tests, were also analyzed. FENO (28.5 ± 16 ppb vs 30.9 ± 17.2 ppb,p= 0.72) and CANO (4.4 ± 3.5 ppb vs 3.2 ± 1.7 ppb,p= 0.73) levels did not differ significantly between patients with or without SAPF, even when dividing them according to treatment or disease activity. CANO appeared reduced in patients with active sarcoidosis (2.1 ± 0.8 ppb vs 4.1 ± 3 ppb,p< 0.05). In conclusion, CANO cannot be considered a biomarker of SAPF. Its lower level in patients with active disease confirms the prevalence of Th1 inflammation in granuloma formation and suggests its potential role as a biomarker of active pulmonary sarcoidosis, but further studies with larger samples are needed to confirm this hypothesis.

The concentration of angiotensin converting enzyme (ACE) and that of albumin (AIb) were assayed in the serum (SACE, SAlb) and in bronchoalveolar lavage fluid (LACE, LAlb). Three groups of patients were studied: 14 healthy volunteers (Group I), 45 patients with active sarcoidosis (Group II), and 7 patients with sarcoidosis in remission (Group III). The SACE in Group II (4,466 +/- 2,202 U/100 ml, mean +/- SD) was higher (p less than 0.001) than in Group I (2,470 +/- 547 U/100 ml) or in Group III (2,640 +/- 610 U/100 ml); LACE was higher in Group II (65.2 +/- 48.4 U/100 ml, p less than 0.001) than in Group I (21.1 +/- 14.7 U/100 ml), or in Group III (25.7 +/- 14.6 U/100 ml). The SAlb was found to be, respectively, 3,908 +/- 385 mg/100 ml, 3,982 +/- 965 mg/100 ml, and 3.613 +/- 222 mg/100 ml in Groups I, II, and III. The LAlb in Group II (8.2 +/- 6.2 mg/100 ml) was higher (p less than 0.01) than in Group I (2.5 +/- 1.4 mg/100 ml) or in Group III )4.1 +/- 1.0 mg/100 ml). The LACE in Group II increased with the number of alveolar lymphocytes, in nonsmokers (4 = + 0.56, df = 34, p less than 0.001) and in smokers (4 = + 0.88, df = 7, p less than 0.01). In the smokers in this group, LACE was higher with respect to the number of lymphocytes than in the nonsmokers. We conclude from this study (1) that the permeability of the alveolocapillary membrane to albumin and to ACE is increased in active pulmonary sarcoidosis, (2) that LACE increases during sarcoidosis and returns to normal when the disease is cured, and (3) that the concentration of ACE in alveolar fluid increases with tobacco use.

Sarcoidosis is a multisystem inflammatory disease of unknown aetiology. Skin involvement has been reported in 12%–27% of patients with systemic disease, and scar sarcoidosis is a form of sarcoidosis developing in previous cutaneous scar areas. Scars due to all kinds of trauma, including surgery, vaccines, cosmetic tattoos, and herpes zoster infection, have been reported to be associated with sarcoidosis. Upper eyelid blepharoplasty is a mainstay of aesthetic procedure and of surgical rejuvenation of the orbital region. There have been relatively few reported scar sarcoidosis on blepharoplasty scar, considering many blepharoplasty procedures done for the last century. We report a case of 47-year-old woman presented with abruptly forming bilateral scar sarcoidosis on upper eyelid linear scars of 20 years of duration.
