“…Usually, these nests are demarcated by half-moon peripheral clefts (“capping”), and even isolated epidermal melanocytes can be delimited (“microcapping”). A small amount of mitosis can be found mainly at the center of the neoformation; rarely at the edges or base [3, 6]. All of these characteristics were found in our patient.…”

Introduction: Spitz nevus is an uncommon, benign melanocytic proliferation that primarily appears on face, trunk or lower extremities of children. This lesion may share clinical and microscopical characteristics with melanoma, making it a diagnostic and management challenge. Case Report: A 13-year old male presented with an asymptomatic chronic dermatosis located on the third left-hand nail. Cutaneous examination revealed a homogeneous dark brown melanonychia which extended up to the cuticle. Upon dermoscopy, longitudinal bands measuring less than 3 mm wide of heterogeneous colors ranging from light to dark brown, and positive Hutchinson’s sign were observed. Discussion/Conclusion: We report the second case of a Spitz nevus ungually localized which strongly resembled an ungual melanoma with a positive Hutchinson’s sign upon dermoscopy. Describing the infrequent presentation and location of the Spitz nevus poses an opportunity to establish diagnostic and management criteria in the near future.

“…Of note, however, there does not appear to be a gender predilection in cutaneous balloon cell nevi. 18 Because of the rarity of conjunctival balloon cell nevi, and given that excision was the treatment for all cases, their natural history remains unknown. The rate of recurrence after excision is also unclear as only three reports comment on recurrence, with one case having multiple recurrences 24 and two cases without recurrence after 4 and 6 months.…”
