Myofibroma of the gingiva: a rare case report and literature review

Postauricular Myofibroma of the Facial Canal: A Case Report

Myofibromatosis is a proliferative disorder characterized by the development of soft tissue neoplasms referred to as myofibromas that predominantly occur in infants and young children. These lesions have been described using varied terminologies since they were first reported in 1951. However, these neoplasms are histopathologically characterized by benign fibroblast and myofibroblast proliferation containing a biphasic presentation of spindle-shaped cells surrounding a central zone of less differentiated cells arranged in a hemangiopericytoma-like pattern in all cases. Usually, myofibromatosis occurs in children aged <2 years and is observed at birth in nearly 60% of cases. We report a rare case of myofibroma in an 8-year-old boy who presented with an approximately 6-month history of a left postauricular mass. Histopathological evaluation of the resected mass confirmed the diagnosis.

Unilateral buccal space masses: a case series

The head and neck region consists of several potential tissue spaces that are formed by the fascial layer. The buccal space is an area of anatomic significance due to its small size and distribution of adipose tissue. Unilateral buccal space masses often pose a diagnostic challenge owing to the diversity of tissues in the area. Here, we report four such cases of buccal space masses arising from different tissues, which presented as unilateral buccal space swelling. This report also highlights the various causes and the differential diagnoses of unilateral buccal space masses.

Myofibroma as a Rapidly Growing Gingival Mass in a 4-year-old Boy: a Case Report

Solitary myofibroma is an uncommon benign soft tissue neoplasm of myofibroblastic origin exhibiting head and neck region predilection but its presence in the jaws is rare. Myofibroma presents as painless mass and may demonstrate rapid enlargement and growth that clinically mimic malignancies. This report presents a 4-year-old male patient with a rapidly growing mandibular gingival mass with some evidence of underlying alveolar bone destruction. Incisional biopsy was performed and the specimen was stained with hematoxylin and eosin and immunohistochemical antibodies for αSMA, CD34, S100 and desmin. The diagnosis of myofibroma was made and the lesion was completely excised. The knowledge about microscopic features of this rare neoplasm helps to have a proper diagnosis and avoid unnecessary treatment.

Solitary Myofibroma of the Mandible in a Six-Year Old-Child: Diagnosis of a Rare Lesion

Myofibroma is a benign uncommon fibroblastic tumour originating from the soft tissue, bone and may affect both children and adults. Radiographically myofibroma presents as unilocular radiolucency. Histologically, typical biphasic cellular arrangement is noted. Immunohistochemical markers are useful for definitive diagnosis of this uncommon neoplasm. Here, a case of six-year-old male child with a localized swelling in the left body of mandible is presented. The clinical, radiological, histological and immunohistochemical findings were corroborative of Infantile Myofibroma.
