BRENNER, Fabiane Mulinari et al. Alopecia: an uncommon cutaneous manifestation of sarcoidosis. An. Bras. Dermatol. [online]. 2008, vol.83, n.5, pp.437-440. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962008000500007.
Sarcoidosis is a multi-system granulomatous disease that generally affects the respiratory tract and hilar lymph nodes. The skin is also commonly involved, although cutaneous sarcoidosis on the scalp is rare. Two cases of scalp sarcoidosis are reported: the first presented with patchy alopecia, cutaneous sarcoidosis and also systemic disease in a black patient; the second case is related to an uncommon presentation with alopecia as the single cutaneous manifestation in a Caucasian patient with pulmonary sarcoidosis. Scalp sarcoidosis deserves special attention because there is a high incidence of other systemic lesions with this cutaneous manifestation, thus a careful investigation should be performed in these patients.
