Primary mucinous carcinoma of skin with a trichoadenomatous component: A rare case report.

Primary mucinous carcinoma of the skin is a rare subtype of eccrine sweat gland tumors. Differentiating it from metastatic adenocarcinomas is important in the management of this condition. We report the case of a 55-year-old female presenting with a painless nodule, which was subsequently diagnosed as primary mucinous carcinoma of skin with a trichoadenomatous component.

Elastosis perforans serpiginosa in a case of pseudoxanthoma elasticum: A rare association.

Elastosis perforans serpiginosa (EPS), characterized by transepidermal elimination of fragmented elastic fibers, clinically presents as hyperkeratotic papules. EPS is classified into three types: (1) Idiopathic; (2) reactive, with associated connective tissue diseases such as pseudoxanthoma elasticum (PXE), Ehlers-Danlos syndrome, cutis laxa, Marfan syndrome, osteogenesis imperfecta, Down's syndrome; (3) the one that is induced by D-penicillamine. A rare association of EPS with PXE, which is primarily a defect of transmembrane transporter protein with accumulation of certain metabolic compounds and secondary calcification of elastic fibers has been documented in the literature.

Childhood lichen planus pemphigoides triggered by chickenpox.

Lichen planus pemphigoides (LPP) is a rare autoimmune bullous disorder that is rarer in children characterized by bullae on lichen planus like papules and the normal looking skin. Clinical, histopathological and direct immunoflourescence evaluation is important for the diagnosis of this entity. We report a case of LPP in a 5-year-old girl child probably triggered by an episode of preceding varicella.

Berardinelli-Seip congenital lipodystrophy in two siblings.

Berardinelli-Seip congenital lipodystrophy (BSCL) is a very rare autosomal recessive disorder characterized by various dermatological and systemic manifestations such as lipoatrophy, hypertriglyceridemia, hepatomegaly, acanthosis nigricans, and acromegaloid features. BSCL type 2 is more common and severe, with onset in the neonatal period or in early infancy. The locus for BSCL2 has been identified on chromosome 11q13.
