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...

Eosinophilic granuloma was formerly mistaken for “eosinophilic myeloma” (Finzi 1929) or for “osteomyelitis with eosinophilic reaction” (Schairer 1938). It was described as a new distinct entity by Otani and Ehrlich (1940) under the denomination solitary granuloma of bone and by Jaffe and Lichtenstein (1944) as eosinophilic granuloma ofbone. Farber(l94l) and Green and Farber (1942) showed that e...

central giant cell granulomas (cgcgs) may manifest as radiolucencies anywhere in the mandible or maxilla. in rare cases, it can appear as a localized periradicular area and mimic an endodontic lesion. this case report presents an uncommon location of cgcg which was not accurately diagnosed nor timely treated. periodic follow ups of periapical radiolucencies after rct are necessary. dentists sho...

sarcoidosis is multi organ disease with cutaneous manifestation in 20%-35% patients. cutaneous sarcoidosis has variable manifestations that make it difficult to diagnose. so clinical, histopathologic and laboratory evaluation is needed for diagnosis. most of cutaneous lesions presents as nodul, maculopapule and plaque. morpheaform lesion is a rare presentation of cutaneous sarcoidosis. this cas...

background: granulomatous dermatoses are common skin pathology, often need histopathological confirmation for diagnosis. histologically six sub-types of granulomas found in granulomatous skin diseases- tuberculoid, sarcoidal, necrobiotic, suppurative, foreign body & histoid type. the aims of the present study were clinico-pathological evaluation of granulomatous skin lesions and their etiol...

Granuloma inguinale is a chronic bacterial infection that frequently is associated with other sexually transmitted diseases. Granuloma inguinale is characterized by intracellular inclusions in macrophages referred to as Donovan bodies. Granuloma inguinale usually affects the skin and mucous membranes in the genital region, where it results in nodular lesions that evolve into ulcers. The ulcers ...
