DR [page 4] [Dermatology Reports 2011; 3:e3] Becker nevus on the neck with ear involvement Khalid Mohammad Al Aboud Department of Dermatology, King Faisal Hospital, Makkah, Saudi Arabia Abstract This is a concise observation of Becker nevus located on the right side of the neck with involvement of the ear. Case Report A 30-year old man presented with a hyper- pigmented patch on the right side of the neck that extended to the right ear (Figure 1). The lesion appeared during adolescence and grad- ually increased in size. No increase in hairs were observed in the lesion. There was no his- tory of preceding drug intake nor associated systemic diseases. Skin biopsy showed hyper- pigmentation of basal cell layer on histopathol- ogy and there were smooth muscles in the der- mis. The picture was consistent with Becker nevus. Becker nevus (BN) is an uncommon cutaneous hamartoma. It usually presents in adolescence as a unilateral, hyperpigmented, hairy patch or plaque, often seen on the upper trunk.1-4 BN may involve other sites in the body like the head or the limbs. Cephalic BN may pres- ent with asymmetrical growth of beard hairs.4 Alfadley et al.,3 reported 12 cases of BN with atypical features. Only one of them was a female with BN involving the left side of the neck. It was associated with hypertrichosis. AlGhamdi et al.,2 reported 11 cases with atypi- cal features; only one of them that involved the chin and neck was a 5-year-old boy with BN. It was also associated with hypertrichosis. None of the above two cases involved the ear. The present case is different as it involved the external ear and was not associated with hypertrichosis. In contrast to widely held belief, I concur with others2,3 that cases of BN in atypical loca- tions like the neck are not uncommon and may be under-reported. References 1. Al Aboud K, Al Hawsawi K.
