“…Such lesions can be ulcerated or non-ulcerated and may exhibit variable pigmentation with combinations of blue-gray, red, and white/yellow colors [ 4 , 6 – 8 , 10 , 12 – 14 ]. Additionally, atypical pilomatricomas with an anetodermic appearance have also been reported [ 5 , 9 , 11 ]. In the literature, ultrasound was used to confirm, support or exclude the diagnosis of pilomatricoma [ 18 , 19 ].…”

“…In contrast, dermoscopy of atypical pilomatricoma has rarely been reported in the literature [ 7 , 8 , 11 , 13 – 15 ]. Several authors have described nodules characterized by yellowish lobules on an erythematous background, surrounded by crown-like branching vessels features that can also be found in molluscum contagiosum, which must be considered as a differential diagnosis [ 7 , 13 ] .…”

“…Histology was required to exclude a calcified hemangioma. In addition, Dev et al reported three cases of anetodermic pilomatricoma, which is extremely rare and presents clinically with a scar-like appearance [ 11 , 15 ]. Dermoscopy is inconclusive in these cases and dermoscopic-histopathological correlation is essential to differentiate between dermatofibroma and dermofibrosarcoma protuberans [ 15 ].…”

Introduction: Pilomatricoma is a benign adnexal dermal or subcutaneous tumor derived from immature hair matrix cells. Objectives: The aim of our study is to evaluate clinical and dermoscopic features of pilomatricomas, with a specific focus on pediatric lesions, and to provide a concise review of the existing literature. Methods: A single-center retrospective study was undertaken on 55 patients with a histopathological diagnosis of pilomatricoma referred to the Dermatology Unit, University of Bologna, Bologna, Italy, between 2005 and 2023. Pilomatricomas were retrospectively evaluated relying on clinical and dermoscopic images. A PubMed search was conducted. All the relevant research up to July 31, 2023, was reviewed. We classified the cases as “typical” or “atypical” based on whether they were suspected of being pilomatricomas or not. Results: A total of 55 children with pilomatricomas.were observed and studied. Two patients presented with 2 pilomatricomas, leading to the identification of 58 pilomatricomas. Typical’ pilomatricomas were observed in 79% of cases as nodular and pigmented lesions with one or more colors, ranging from blue-gray to red to yellow/white, evident on clinical examination and even better on dermoscopy. In 21% of cases, pilomatricomas presented in an ‘atypical’ form, which did not allow for a well-founded suspicion, placing them in differential diagnosis with other lesions and therefore requiring histological examination. Conclusions: According to our case series and systematic review of the literature, clinical appearance and dermoscopy may be sufficient to diagnose or suspect pilomatricoma in around 80% of cases, while histological examination is necessary to confirm the diagnosis in the remaining 20% of cases.
