Case for diagnosis. Solitary violaceous nodule on the toe

An. bras. dermatol; 93 (4), 2018
Abstract: Reticulohistiocytomas represent a group of benign histiocytic dermal proliferations, which occur either sporadically as solitary cutaneous nodules or, when multiple, in association with systemic disease. Due to its nonspecific clinical presentation, reticulohistiocytoma may mimic other benign o...

Acquired elastotic hemangioma, a little-known entity: report of a case with 15 years of evolution

Abstract: Acquired elastotic hemangioma is a hemangioma variant first described in 2002. It is characterized by being a benign, solitary, slow-growing lesion, that appears in adulthood and is associated with solar exposure.

Dermoscopy in tinea manuum

An. bras. dermatol; 93 (3), 2018
Abstract: Tinea manuum is a dermatophytosis which is often mistaken for other keratodermas, especially palmar psoriasis and chronic hand eczema. We report the use of dermoscopy as a diagnostic aid in a case of tinea manuum. The dermoscopic clue turned out to be the presence of whitish scaling located mai...

Effluvium telogen occurs in the setting of systemic activity of the disease, and cicatricial alopecia results from discoid lesionsin on the scalp. Other types of alopecia, like alopecia areata, may r...

Sclerodermiform basal cell carcinoma: how much can we rely on dermatoscopy to differentiate from non-aggressive basal cell carcinomas? Analysis of 1256 cases

An. bras. dermatol; 93 (2), 2018
Abstract: Background: The behaviour of each basal cell carcinoma is known to be different according to the histological growth pattern. Among these aggressive lesions, sclerodermiform basal cell carcinomas are the most common type. This is a challenging-to-treat lesion due to its deep tissue invasion, r...

Abstract: Inflammatory breast cancer is an aggressive and infiltrative malignancy that is often misdiagnosed as an infection because of its symptoms and signs of inflammation, delaying proper diagnosis and treatment. We report a case of inflammatory breast cancer showing correlation between dermoscopic a...
