Naked sarcoidal granulomas are supposedly characteristic, but not pathognomonic of sarcoidosis. Other types of histopathological pattern can also happen in sarcoidosis and may lead to misdiagnosis. Thirteen archival skin specimens taken from 10 patients were retrieved from our fi le for study. All patients were labeled as sacroidosis based on histological evidence of noncaseating granuloma foun...

ransepidermal elimination is a disorder in which T dermal stimuli profoundly effect the behavior and structure of the overlying epidermis. Briefly, there are two categories of disorders: the first are primary dermatoses and consist of elastosis perforans serpiginosa and reactive perforating collagenosis; the second group originates from alterations of dermal constituents in preexisting disorder...

Several dermatoses are routinely associated with diabetes mellitus, especially in patients with chronic disease. This relationship can be easily proven in some skin disorders, but it is not so clear in others. Dermatoses such necrobiosis lipoidica, granuloma annulare, acanthosis nigricans and others are discussed in this text, with an emphasis on proven link with the diabetes or not, disease id...

Both clinical and pathologic findings must be considered when diagnosing figurate skin lesions, which are often seen in routine practice. Although a skin biopsy may sometimes be diagnostic, more often the information provided is nonspecific. In an attempt to offer an approach to diagnosing these dermatoses, we have classified annular lesions according to the presence of lymphocytic, neutrophili...

Granuloma annulare (GA) is classified as localized, generalized/disseminated, subcutaneous, and perforating types. The studies show connection with diabetes mellitus, lipidic metabolic disorders, malignant diseases, thyroid disorders, infections (HBV, HCV, HIV). We performed a retrospective study between 2010-2011, regarding disseminated GA (GAD), and the relationship between GAD and other como...

We present a 27-year-old male with multiple nonpainful soft tissue masses over several metacarpals, bilateral elbows, the left wrist, and both knees since the age of 4. Physical exam was significant for firm, nonmobile, nodular growths over the extensor surfaces of bilateral elbows and knees and on the 2nd and 5th metacarpal phalangeal joints. Laboratory studies revealed an unremarkable rheumat...
