Tubular apocrine adenoma clinically and dermoscopically mimicking basal cell carcinoma

Regressing seborrheic keratosis - clinically and dermoscopically mimicking a regressing melanoma.

The diagnosis of seborrheic keratosis is a clinical diagnosis. In a certain percentage of cases, differential diagnosis between seborrheic keratosis and malignant melanoma is difficult. We describe a case of regressing seborrheic keratosis simulating malignant melanoma. Clinical, dermoscopic and histopathologic examinations were performed for the occurrence of an asymmetric, irregularly demarca...

Microcystic adnexal carcinoma mimicking basal cell carcinoma

CLINICAL PRESENTATION A 42-year-old man presented with a 5-year history of an asymptomatic slow-growing papule on the left scapular region. The physical examination revealed a well-defined, 1.2-cm diameter, firm, domeshaped papule with a white-pinkish center, peripheral small papules with a pearly appearance, and a hyperpigmented outer rim (Fig 1). The initial clinical impression suggested basa...

Tubular Apocrine Adenoma – Case Report and Systematic Review

Metanephric adenoma mimicking renal cell carcinoma.

Metanephric adenoma is a rare benign tumour of the kidney, recently recognised as a unique pathological entity which is radiologically indistinguishable from malignant renal tumours. Inability to achieve a precise preoperative diagnosis could lead to a radical surgical approach for this benign tumour with an excellent prognosis. Only a few cases are reported worldwide, and we document the first...

Syringocystadenoma papilliferum combined with a tubular apocrine adenoma*

Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign sweat gland tumors. Syringocystadenoma papilliferum occurs alone or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. However, the co-existence of these two tumors witho...
