LISE, Michelle Larissa Zini et al. Eccrine angiomatous hamartoma: a painful tumor. An. Bras. Dermatol. [online]. 2003, vol.78, n.4, pp. 465-474. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962003000400008.
Eccrine angiomatous hamartoma (EAH) is a benign lesion usually present at birth. In most cases it presents as a flesh-colored or erythematous nodule or patch. It may or may not be associated with focal hyperhydrosis and pain. It is most commonly located in the lower extremities, near the knee or on the toes, but lesions on the face, sacral and cervical region and trunk have been described. The main differential diagnosis should be made with a glomus tumor. In general, EAH shows benign behavior, and spontaneous remission of pain has been described. Cases have been reported in which the pain led to excision and even to amputation of the affected member. The authors present a case of late onset EAH, with exuberant symptoms, which was difficult to treat.
