An Interesting Case Report of Trichodysplasia Spinulosa in a Case of B-cell Lymphocytic Leukemia

Trichodysplasia spinulosa (TS) is a rare dermatologic condition characterized by follicular-based shiny papules and alopecia with characteristic histopathologic findings. This condition is unique to patients with TS-associated polyoma virus infection who are already immunocompromised. We present one such case of a 10-year-old male, who presented with spiny papules all over the body within a span of 1 month which could not be categorized into any other follicular keratinization disorder on the basis of dermoscopy and histopathology. Our case is unique in the aspect that the patient developed the rash after completion of his chemotherapy. Furthermore, dermoscopy of such a case was not highlighted in earlier literature.
