Mucinous eccrine naevus: case report and review of the literature

Facial eccrine angiomatous hamartoma in a 52-year-old woman: A case report

Eccrine angiomatous hamartoma is a rare, benign condition. Patients typically present with a solitary, sometimes enlarging nodule of the extremities usually appearing at birth or arising during childhood. Eccrine angiomatous hamartoma is usually sporadic, but one familial case of the multifocal variant has been reported. It is recognized histologically by increased numbers of eccrine elements as well as numerous vascular channels and proliferation of other dermal elements such as adipose tissue and hair follicles. When symptomatic, eccrine angiomatous hamartoma may be associated with hyperhidrosis or pain. We report a case of a 52-year-old woman with eccrine angiomatous hamartoma on the face and share our experience with botulinum toxins in the treatment of this condition.

Eccrine Nevus in the Forearm of a 16-Year-Old Presenting as Unilateral Hyperhidrosis: A Clinicopathological Correlation Paradigm

A case of a purely eccrine nevus in an adolescent patient presenting with focal hyperhidrosis on an area comprising the left forearm and the dorsal aspect of the left hand is described. No clinically evident lesions were identifiable. Dermatopathologic findings were subtle, showing only a slight increase in the number of eccrine glands. Clinicopathological correlation was paramount to achieve the diagnosis.

Congenital eccrine angiomatous hamartoma: Expanding the morphologic presentation and a review of the literature

Eccrine angiomatous hamartoma (EAH) is a rare benign vascular hamartoma characterized histologically by an increased size and number of mature eccrine glands associated with multiple foci of dilated capillaries in the dermis and subcutis. EAH typically presents in children as discrete, solitary nodules, or plaques most commonly located on the extremities. Some cases of EAH have an agminated distribution involving classic locations, or present as solitary lesions in less common locations such as the face, scalp, or trunk. We report the case of congenital EAH in a child with atypical morphological features and pattern of distribution further expanding on the range of presentations classically described.

Coccygeal Polypoid Eccrine Nevus Presenting as a Skin Tag: Case Report and Review of the Literature

Coccygeal polypoid eccrine nevi (CPEN) are rare, benign, cutaneous polypoid lesions localized to the coccyx region that are characterized by areas of hyperplastic eccrine ducts without hyperhidrosis. We present the case of an asymptomatic 16-month-old female with a congenital lesion in the lower sacral area and review the literature and the differential diagnosis for CPEN.

Eccrine Nevus Presenting with Umbilical Discharge: A Case Report and Review of the Literature

Eccrine nevus is a rare skin lesion with protean manifestations like hyperhidrosis, discolored nodules, papules, and so forth, which has been reported in various anatomic parts of the body including the forearm, leg, thigh, back, and coccyx. Our patient was a 26-year-old male, who presented with increasing colorless and odorless episodic umbilical discharge. First impression for the patient was an umbilical sinus and the patient underwent surgery. Histopathological study revealed the lesion to be an eccrine nevus of the umbilicus. This is the first case of eccrine nevus presenting with umbilical discharge. We recommend that eccrine nevus should be considered as a differential diagnosis for umbilical discharge.
