Blueberry muffin rash as a presentation of alveolar cell rhabdomyosarcoma in a neonate.
Soft tissue sarcomas of childhood continue to present problems with pathologic diagnosis, staging and treatment. Rhabdomyosarcoma, the most common soft tissue sarcoma, represents 4-8% of all malignant solid tumours in children. We report a case of congenital alveolar rhabdomyosarcoma who presented with "blueberry muffin"-like rash. A full-term female infant was noted at birth to have multiple skin lesions resembling blueberry muffin rash and an abdominal mass in the left iliac fossa, which appeared to be fixed to the posterior abdominal wall. There was no enlargement of liver and spleen, but her para-aortic lymph nodes were enlarged. Biopsy from the mass confirmed the diagnosis of alveolar cell rhabdomyosarcoma. Molecular investigation for the t (2:13) translocation was negative. The infant received chemotherapy but died within 1 mo of diagnosis.
