Background: In approximately 65% of patients, mastocytosis presents between birth and 15 years of age. Although solitary mastocytomas usually appear within the first 3 months of life, in unusual circumstances they may appear in adulthood.
Objective: The rare entity of solitary mastocytoma in adulthood and the simple treatment method of excision are discussed.
Methods: Simple surgical excision without manipulation of the lesion was performed.
Results: The lesion was surgically excised without recurrence.
Conclusion: Solitary mastocytoma is a rare lesion in adulthood. The differential diagnosis includes a melanocytic nevus, xanthogranuloma and leukemia cutis. Surgical excision offers a rapid, relatively simple and effective mode of treatment.
