Vitiligo-like lesions of mycosis fungoides coexisting with large plaque parapsoriasis: An association or a spectrum?

Abstract

Mycosis fungoides is the commonest type of primary cutaneous T cell lymphoma. Hypopigmented mycosis fungoides is an uncommon variant usually observed in dark-skinned individuals, especially children. Large plaque parapsoriasis, a disease of the middle-aged, and with no racial and geographical predilection, can be regarded as the clinically benign end of the mycosis fungoides disease spectrum. Case of a 24-year-old male, with asymptomatic hypopigmented lesions with characteristics of large plaque parapsoriasis, and vitiligo-like skin lesions with characteristics of mycosis fungoides developing over pre-existing hypopigmented lesions, with no systemic features, is presented for its unusual clinical features and conspicuous histopathological findings.
