Resumen
DELGADILLO JORDAN, Camila et al. Solitary mast cell tumor. A case comunication. Rev. alerg. Méx. [online]. 2022, vol.69, n.3, pp.142-145. Epub 19-Mayo-2023. ISSN 2448-9190. https://doi.org/10.29262/ram.v69i3.1107.
Background:
The solitary cutaneous mastocytoma is a variant of cutaneous mastocytosis which carries a good prognosis. It may develop at a very early age, during the first weeks of life, or even be congenital. Typically, they present as red-brownish lesions that may be asymptomatic or present systemic manifestations associated with histamine release.
Case report:
A 19-year-old female patient who attended a medical consultation for a pigmented lesion, slightly raised in the left antecubital fold, asymptomatic, of recent appearance and progressive growth. Dermoscopy reported a fine symmetrical network, yellowish-brown in color and randomly distributed black dots. The pathology report and immunohistochemical findings were consistent with mast cell tumor.
Conclusion:
The solitary cutaneous mastocytoma should not be considered as an exclusive entity in the pediatric population. Acknowledgment of its atypical clinical presentation with its dermatoscopic features, is useful for diagnosis.
