Granulomatous slack skin: cytogenetic and molecular analyses.

Granulomatous slack skin (GSS) is a rare disorder which is considered a slowly evolving T-cell lymphoma associated with granulomatous inflammation that mediates clastolysis. A combined cytogenetic, molecular, and cellular analysis was conducted on a clinically and histologically defined case of GSS. Cell cultures obtained from the skin biopsy showed trisomy of chromosome 8, and the DNA sample extracted from the skin biopsy showed a T-cell receptor beta-chain rearrangement.
