Solitary pink papule in an elderly man

A 72-year-old, healthy man presented with an asymptomatic, stable, solitary, 5-mm × 5-mm, pink, dome-shaped papule on his neck that had been present for at least 6 months (Fig 1). There were no identifiable triggers, including exposure to drugs, radiation, or trauma to that area. A physical examination was unremarkable and did not demonstrate lymphadenopathy or hepatosplenomegaly. Polarized dermoscopy demonstrated a homogeneous, pink papule with serpentine, dotted, and short linear vessels; white, shiny lines; and white rosette structures (Fig 2). Pathology showed a heavy infiltrate of intermediate-to-large, atypical lymphoid cells involving the papillary dermis, dermoepidermal junction, and epidermis. The atypical lymphoid cells monotonously stained for CD3, diffusely expressed CD30 and nuclear MUM1 (bright), and were double-negative for CD4 and CD8 (Figs 3 and 4). ALK-1, SOX10, PD1, and CD138 were negative. No further investigations were undertaken.Fig 2View Large Image Figure ViewerDownload Hi-res image Download (PPT)Fig 3View Large Image Figure ViewerDownload Hi-res image Download (PPT)Fig 4View Large Image Figure ViewerDownload Hi-res image Download (PPT)Question 1: Given the history and images, what is the most likely diagnosis?A.Primary cutaneous anaplastic large cell lymphoma with 6p25.3 rearrangementB.Transformed CD30+ mycosis fungoides (MF)C.Lymphomatoid papulosis (LyP) with 6p25.3 rearrangement (LyP 6p25.3)D.LyP type CE.LyP type BAnswers:A.Primary cutaneous anaplastic large cell lymphoma with 6p25.3 rearrangement – Incorrect.
