A Case of Lymphomatoid Papulosis Limited to Becker's Melanosis

Abstract

Regional lymphomatoid papulosis (LyP) accounts for 2-27% of all LyP cases. Several localized dermatoses have been reported in association with Becker's melanosis (BM), e.g. acneiform lesions or lichen planus. Here, we report on regional LyP confined to the area of BM. A 56-year-old man presented with a 1-year history of a steadily increasing number of multiple pruritic red papules developing on the area of BM, which had occurred on his left shoulder during puberty. Histopathological analysis was consistent with regional LyP. Potent topical steroids followed by oral doxycycline did not achieve improvement, while long-term oral bexarotene treatment ameliorated the skin condition. Recently, the proposed entity of ‘persistent agmination of LyP' (PALP) has extended the clinicopathological observations of regional LyP. Since PALP remains controversial, a unifying concept of localized LyP and PALP will be discussed.

CD30‐positive lymphoproliferative disorder in a red tattoo: regional lymphomatoid papulosis typeCor pseudolymphoma?

“…LyP is known for its spontaneously relapsing and remitting nature, with a high rate of spontaneous regression . Regional forms of LyP account for 2–27% of all cases of LyP . Although there have been a number of reports of pseudolymphomatous reactions in tattoos, the association of regional LyP within a tattoo has not previously been reported.…”

Becker’s Nevus with Lichen Simplex Chronicus Limited to the Nevus Lesion: A Case Report

“…Several dermatoses have been reported in association with Becker's nevus. Box 1 shows a select list of these skin conditions (1)(2)(3)(4)(5)(6)(7)(8).…”

Becker's Nevus with Recurrent Eczema Limited to the Nevus Lesion

“…Lesions are usually asymptomatic and rarely associated with several dermatoses and structural abnormalities. Skin diseases such as acneiform lesions 1 , lichen planus 2 , prurigo nodularis 3 , hypohidrosis 4 , lymphomatoid papulosis 5 , desmoid tumor 6 , localized scleroderma, leiomyoma cutis, and plexiform neurofibroma 7 have been reported in association with Becker's nevus. Structural abnormalities associated with Becker's nevus include breast hypoplasia, supernumerary nipples, aplasia of the pectoralis major muscle, ipsilateral limb shorting, segmental odontomaxillary dysplasia, and lipoatrophy 3 7 .…”
