Neutrophilic dermatosis of the dorsal hands associated with a "myeloproliferative neoplasm, unclassifiable" and a simultaneous cancer of colon.

Neutrophilic dermatosis of the dorsal hands is a variant of Sweet's syndrome. We herein describe an 83-year-old woman with a neutrophilic dermatosis of the dorsal hands associated with a "myeloproliferative neoplasm, unclassifiable" and a simultaneous cancer of colon. To our knowledge, and after a search in PubMed, the association of Sweet's syndrome with a "myeloproliferative neoplasm, unclassifiable" and a simultaneous cancer of colon has not previously been reported.

[Desmoplastic trichoepithelioma: presentation of two cases].

Trichoepithelioma is a benign neoformation with hair follicle differentiation that may clinically present in solitary, multiple or desmoplastic form. From a histopathological standpoint, it poses some diagnostic difficulties with basal cell carcinoma. We present two cases of desmoplastic trichoepithelioma, a rare adnexal tumor whose incidence is estimated at 2 per 10,000.
