Eccrine angiomatous hamartoma.

BACKGROUND

Eccrine angiomatous hamartoma (EAH) is a rare benign lesion that mimics a capillary ("strawberry") hemangioma (CH) in appearance. EAH slowly grows and becomes symptomatic whereas CH typically regresses over time.

OBJECTIVE

To increase awareness of this rare hamartoma and emphasize the need for histopathologic evaluation of similar appearing lesions and thus prompt excision versus observation.

METHODS

Literature review and report of an illustrative case.

RESULTS

Histopathologic confirmation of EAH in a lesion clinically indistinguishable from CH and successful surgical extirpation.

CONCLUSIONS

EAH is a rare hamartomatous neoplasma clinically similar to CH in appearance. Histopathologic examination of suspected lesions is recommended for delineation as CH generally involutes spontaneously whereas EAH may require surgical excision due to pain and hyperhidrosis.
