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.

Mucinous eccrine naevus: case report and review of the literature

Mucinous eccrine naevus (MEN) is an extremely rare variant of eccrine naevus. There are only nine reported cases in the English literature. We report a 3-month-old boy with a congenital lesion on the lower back, and review the other cases in the literature. In most cases, MEN presents before puberty. The commonest presentation is a unilateral, solitary, brownish nodule without hyperhidrosis occurring on the legs. The diagnosis of this condition is confirmed by the characteristic histopathological features. Treatment options may be considered if symptomatic.

Eccrine angiomatous hamartoma mimicking a traumatic hemorrhage

Eccrine angiomatous hamartoma (EAH) is a rare benign disease that is characterized by an abnormal proliferation of eccrine glands and vascular elements. It is generally congenital, but it can appear before puberty. It usually presents as a single plaque or nodule, but multiple patch-like lesions are also possible. EAH is mostly asymptomatic, but it is sometimes associated with pain or hyperhidrosis. It generally does not require aggressive treatment, but the lesion can be excised due to pain, enlargement and cosmetic reasons. A 3-week-old Korean female presented with a hemorrhagic skin lesion on the right foot since birth. There was no specific birth history. The lesion first appeared on the third toe of the right foot and quickly spread to almost half of the right foot. Histopathology examination revealed acanthosis in the epidermis and a proliferation of eccrine ducts, glands and capillaries. The eccrine glands were immunohistochemically-positive for carcinoembryonic antigen.

[Eccrine angiomatous hamartoma: a report of 2 cases]

Eccrine angiomatous hamartoma is a rare, benign tumor characterized by a proliferation of eccrine and vascular structures. We present 2 cases and review the characteristics of this disorder. The first patient was a 33-year-old woman who consulted for a brownish lesion on her back associated with local hyperhidrosis. The second patient was a 25-year-old man with an asymptomatic erythematous lesion on his left palm. In both patients a diagnosis of eccrine angiomatous hamartoma was made based on the histological findings. Eccrine angiomatous hamartoma is usually present at birth or develops during childhood. It is typically a solitary lesion and signs and symptoms can vary; diagnosis is therefore based on histological study. The most common site is on the distal parts of limbs. The lesions tend to be asymptomatic, but there may be associated pain and hyperhidrosis. Treatment is not usually necessary except in cases with persistent symptoms, excessive sweating, or cosmetic concerns.

Eccrine angiomatous hamartoma in a child

Eccrine angiomatous hamartoma (EAH) is a rare, benign malformation characterized by both eccrine and vascular components. It usually presents at birth or during early infancy and childhood as a nodule or a plaque, usually solitary, involving acral skin. Eccrine angiomatous hamartoma is usually asymptomatic, although focal hyperhidrosis, hypertrichosis, and pain can be observed. We report an additional case of this rare entity presenting in a 14-year-old boy.

Eccrine angiomatous hamartoma: report of five congenital cases

Eccrine angiomatous hamartoma is a rare entity characterized histologically by the combination of proliferative eccrine and vascular elements. It generally arises before puberty, as solitary or multiple lesions, with a heterogeneous clinical appearance, affecting predominantly the distal extremities, with or without associated pain or hyperhidrosis. It may require surgical treatment due to cosmetic concern, progressive enlargement or the presence of pain or excessive hyperhidrosis. We report five congenital cases of eccrine angiomatous hamartoma, emphasizing a clinically uncommon tumor-like appearance, with numerous telangiectasias on their surfaces resembling vascular lesions, in two of them.
