Dermoscopy of eccrine angiomatous hamartoma: The popcorn pattern

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

“…lesion predominance on the distal extremities (See Table 1) 7,8,[11][12][13][14][19][20][21][22][23] with fewer accounts detailing distribution on the head, neck, and lower back. 3,6,9 Cases reporting lesions in uncommon locations, such as the trunk or abdomen, typically involved only a solitary lesion, whereas EAH occurring as multiple lesions was more often reported in classic sites of involvement such as the arm or leg. 24,25 In a review by Patterson et al, 18 cases were reported including four with multiple lesions, all located on the extremities.…”

“…Onset of EAH is most commonly in children prior to puberty as a solitary, unilateral, variably sized (1‐11 cm), red to violaceous nodule, or plaque located on the extremities . Although rare, there have been reports of multiple EAH lesions occurring within a single patient in a linear, grouped, agminated, or blaschkoid distribution . We report a case of congenital EAH in a child with an atypical distribution and morphology.…”

“…EAH exists on a spectrum of cutaneous tumors that include eccrine nevus, mucinous eccrine nevus, and EAH. Each diagnostic subtype is characterized by an increase in the number as well as size of mature eccrine glands or ducts, with EAH being distinguished by the added vascular component …”

“…Each diagnostic subtype is characterized by an increase in the number as well as size of mature eccrine glands or ducts, with EAH being distinguished by the added vascular component. [3][4][5][6] Patients with EAH may present with complaints of pain or increased sweating associated with stress or exercise, or without any associated symptoms. 3,4 Onset of EAH is most commonly in children prior to puberty as a solitary, unilateral, variably sized (1-11 cm), red to violaceous nodule, or plaque located on the extremities.…”
