- Pilomatricoma is a benign skin growth commonly found on the head, arms, and legs, typically appearing as painless nodules under 3 cm in size.
- The case study discusses an 8-year-old girl with an atypical 5×5 cm lesion on her forearm that did not have the usual firmness of pilomatricoma, which was ultimately confirmed through a biopsy.
- The authors emphasize that the diagnosis of pilomatricoma should consider atypical characteristics, such as larger size, cystic features, pain, or resemblance to keloids, and not just the common presentations.
