Myofibroma of the pinna: a case report and review of the literature

BACKGROUND

Myofibromas are rare mesenchymal tumors with a predilection for the head, neck, and oral cavity. Primarily affecting infants and young children, these tumors typically manifest as superficial painless nodules. Diagnosis is confirmed through histopathological examination of a biopsy, revealing nodules characterized by spindle cell proliferation. To our knowledge, only two cases of pinna myofibroma have been previously reported in the literature.

CASE PRESENTATION

Here, we present the case of a three-year-old male who developed a myofibroma of the left auricle following trauma to the area one year earlier. The patient underwent surgical resection without any postoperative complications. The patient later returned with a lesion consistent with hypertrophic scar.

CONCLUSIONS

This study aims to provide a comprehensive review of the clinical presentation, histopathologic and immunohistochemical features, and surgical management of this unique case of myofibroma of the pinna.

[Myopericytoma: an uncommon chest wall tumor]

Myopericytoma is, according to the World Health Organisation classification of soft tissue tumours, a recently proposed term describing a group of tumours showing a perivascular myoid differentiation. It is a rare tumour with a predilection for the distal extremities and is often misdiagnosed. We report a new case of myopericytoma located exceptionally in the chest wall together with a review of literature.
