atypical fibrous xanthoma
Introduction
Introduction to atypical fibrous yellow tumor Atypical fibromaanoma (atypical fibronanthoma) is a low-grade malignant tumor associated with malignant fibrous histiocytoma. The two are histologically similar, but the atypical fibroids are smaller and the position is shallower. it is good. basic knowledge The proportion of illness: 0.0035% Susceptible people: more common in men and women over 50 years old Mode of infection: non-infectious Complications: sarcoidosis
Cause

Atypical fibrous xanthomas are mainly solid nodules on the skin, which may be accompanied by scarring or erosion. Some repeated scratching may be accompanied by eczema. If you do not pay attention to cleanliness, you may have secondary infection, causing local lymph node inflammation.

Examine
Examination of atypical fibrous xanthoma
Histopathology: The tumor occurs in the dermis and is separated from the epidermis by the collagen band of the cell. The tumor consists of odd-shaped fusiform cells and atypical tissue cells. Some fusiform cells have a vesicular nucleus, and the cytoplasm can be vacuolated. Yellow tumor cells, mitotic figures, significant eosinophilic nucleoli and the appearance of biphasic tumor cell populations are characteristic findings. S-100 protein staining is sparse compared to melanoma, negative for keratin staining, and helps with squamous Cell tumor identification.

According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
