Linear lichen planus and hepatitis C.

A 23-year-old man with hepatitis C was observed with brownish dome-shaped papules in a linear pattern on the chest. The papules were determined clinically and pathologically to be linear lichen planus. These lesions appeared during an interferon-alpha therapy for his hepatitis and resolved after topical treatment with tacrolimus ointment. Linear lichen planus and hepatitis C have been reported only twice previously. The association between these disorders and the potential role of interferon therapy are discussed.

Multiple cutaneous reticulohistiocytomas in a patient with rheumatoid arthritis.

A 64-year-old woman with a long-standing peripheral symmetric polyarthritis with positive rheumatoid serology was evaluated for multiple asymptotic papulonodules of fingers, mentum, lower lip, ears, and eyelids. Histopathologic examination showed a dermal infiltrate composed of histiocytes, multinucleate giant cells with ground-glass cytoplasm, and lymphocytes, suggestive of reticulohistiocytoma. The possibilities of multicentric reticulohistiocytosis with positive rheumatoid serology or coexistence of multiple cutaneous reticulohistiocytomas and rheumatoid arthritis are discussed.
