Basaloid follicular hamartoma has been linked to a mutation in the PTCH-1 gene, which is part of the same pathway involved in Gorlin-Goltz syndrome. Here we present a 9-year-old pa

10. Splenic hamartoma associated with visceral leishmaniasis mimicking aggressive lymphoma
Abstract Pilomatricomas are benign tumors originating from the capillary matrix, which may present as solitary lesions or, less commonly, multiple. Myotonic dystrophy and familial adenomatous polyposis are the most frequently associated disorders with multiple pilomatricomas. There are few reports relating these tumors to other genetic syndromes. Rubinstein-
