[Primary cutaneous mucormycosis. A case report]. / Mucormicosi cutanea primitiva. Riferimento di un caso.

One case of primary cutaneous mucormycosis developed in the hospital environment is reported. Dressings contaminated by hyphae may have been the cause. In diabetic or immunodepressed patients this disease may be fatal. Incisional biopsy is the only diagnostic tool.

Diabetic mastopathy. A report of two cases diagnosed by aspiration cytology.

BACKGROUND: Diabetic mastopathy (DM) is a lymphocytic mastitis that develops in women who have suffered from insulin-dependent diabetes mellitus for some years. CASES: A 51-year-old female with type 1 insulin-dependent diabetes for 13 years presented with a 3-cm, hard, mobile nodule in the right breast. A 59-year-old female on insulin therapy for five years presented with a 4-cm mass in the subareolar region of the breast. The aspirate in both cases showed clusters of ductal cells, some lymphocytes and epithelioid fibroblasts in fragments of dense connective tissue. CONCLUSION: The expected frequency of this disease is far lower than the number of cases diagnosed. This is due to the lack of highly specific criteria for the diagnosis. Only the integration of clinical histories with cytologic findings can lead to an accurate diagnosis and avoid needless surgery.

Desmoplastic malignant melanoma (neurotropic variant).

A case of neurotropic variant desmoplastic malignant melanoma is reported. The report deals with a tumor consisting of dense stroma in which fusiform cells are immersed and whose reduced capacity to produce melanin makes correct diagnosis difficult in the absence of an associated nevus lesion. Immunohistochemical characteristics and possible differential diagnoses are discussed.
