Pleomorphic lipoma of the face: case report

ORAL DISEASES, Issue 1 2006
FO Prado
Pleomorphic lipoma is an uncommon variant of lipoma, which microscopically may resemble a liposarcoma. However, it is a slow-growing and well-circumscribed lesion with a benign behavior. Therefore, recognizing this entity is extremely important to perform the proper treatment. We present an additional case of pleomorphic lipoma in the face, which to our knowledge seems to be the 11th case reported in the English-language literature. [source]

Intradermal spindle cell/pleomorphic lipoma of the vulva: case report and review of the literature

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2002
Jorge S. Reis-Filho
Background: Spindle cell/pleomorphic lipoma (SC/PL) is a benign adipose tissue tumor that usually affects the subcutaneous tissues of shoulders, backs, and neck region of middle-aged male patients. Histologically, it is characterized by the presence of primitive CD34-positive spindle cells arranged in short fascicles, bizarre floret-like multinucleated giant cells, mature adipocytes, and a small number of lipoblasts. Recently, an intradermal subset has been described, which mainly affects female patients and presents a wider antomical distribution when compared to the classical variant of SC/PL. Methods: We report a case of intradermal SC/PL affecting the labium majus of a 56-year-old female patient. Results: The histological examination disclosed the typical histological features, however the lesion showed poorly demarcated and infiltrative borders, as well as involvement of dermal nerves. The immunohistochemical analysis according to streptovidin-biotin-peroxidase technique showed immunoreactivity for CD34 and vimentin in the spindle cells, as well as S100 protein and vimentin in the adipocytic cells. Conclusions: To the best of our knowledge, this is the first case of intradermal SC/PL affecting the vulvar region. Care must be taken not to misdiagnosis this rare tumor as well-differentiated liposarcoma, cellular angiofibroma, solitary fibrous tumor, and cutaneous neurofibroma. [source]
