Diagnosis: Precalcaneal congenital fibrolipomatous hamartoma (PCFH).
MICROSCOPIC FINDINGS AND CLINICAL COURSE
Microscopic examination revealed unencapsulated mature adipose tissue enveloped in fibrous sheaths, consistent with PCFH. No features of neurofibromatosis or immature mesenchymal components, such as brown fat, were identified.
The pedal nodules were resected. Grossly, the nodules were composed of lipomatous material in discrete 2- to 3-mm spheres. There was little cohesion between the individual "caviarlike" lipomatous spheres, and they were easily removed. Three weeks after resection, the patient was walking normally without any apparent discomfort.
DISCUSSION
Precalcaneal congenital fibrolipomatous hamartoma is a rare idiopathic condition. It was first described in 1990 by Larralde de Luna et al,1 who reported 4 cases. Since then, a total of 15 cases have been reported. A variety of names besides PCFH2 have been used to describe this condition, including congenital piezogenic-like pedal papules,3 bilateral congenital adipose plantar nodules,4 and podalic papules in the newborn.5
