Oyster Shell-Like Skin Lesions in a Young Man
An otherwise healthy 30-year-old man presented with oyster shell-like skin lesions (Figure 1) on his scalp, face, trunk, arms, and legs of 1 month’s duration. He denied excessive alcohol ingestion or drug use. Three months ago, he had a high-risk sexual exposure. Physical examination revealed condylomata lata (Supplemental Figure 1, available online at http://www.mayoclinicproceedings.org ) in the perineal and perianal areas. Skin biopsy revealed a dense infiltrate of lymphocytes, plasma cells, and neutrophils in the dermis.Pachydermodactyly
An 18-year-old male presented with a 2-year history of asymptomatic proximal interphalangeal (PIP) joints swelling involving the second, third, and fourth fingers of both hands (Figure 1). No morning stiffness, rashes, or other symptoms were reported. Family history was unremarkable. Range of joint motion was normal. Blood tests including rheumatoid factor, C-reactive protein, HLA-B27, antinuclear antibody, and extractable nuclear antigen were all negative or within normal limits. X-ray of the hands showed soft tissue swelling around PIP joints, without articular narrowing or bony erosions (Figure 2).
