Solitary mastocytoma in an infant - case report with review of literature

[Isolated mastocytoma in children: a case study]

Le mastocytome solitaire est la forme la plus fréquente de mastocytose chez l'enfant. Son pronostic est bon comme toutes les autres formes de mastocytoses de l'enfant avec possibilité de régression spontanée. Les dermocorticoïdes peuvent accélérer cette régression comme c'est le cas chez notre patient.

Solitary mastocytoma of the eyelid

Mastocytosis is a heterogeneous group of diseases characterized by the proliferation and abnormal infiltration of mast cells in tissue. These collections of mast cells are called mastocytomas. Solitary mastocytomas are cutaneous lesions, most commonly involving the extremities and trunk. Rubbing a cutaneous mastocytoma lesion leads to the release of histamine and other chemical mediators causing the lesion to become elevated and urticarial, similar to an allergic reaction. We describe a rare location of a presumed solitary mastocytoma of the lower eyelid in a young otherwise healthy child.

Solitary mastocytoma improved by intralesional injections of steroid

Solitary mastocytoma is an uncommon disease characterized by monotonous infiltrations of mast cells that extend from papillary dermis to subcutaneous fat. They usually resolve by adulthood, and there is no satisfactory treatment other than waiting. A two-month-old Korean male infant with deep solitary mastocytoma was treated intralesionally with triamcinolone acetonide. His mastocytoma in medial malleolus was very distressing because it was very sensitive to friction, and he was just reaching the crawling stage. After three injections, his skin lesion flattened with marked decrease of erythema and subjective symptoms. His skin lesion has continued to have a good clinical response for 9 months after the last treatment.
