Herein, we present a rare case of a young adult male who presented with a soft tissue mass in his right thigh that was excised elsewhere and submitted to us for histopathological review. [ncbi.nlm.nih.gov]

Pathological findings: As per referring laboratory notes, the thigh mass measured 20x9x5 cm, with a tumor measuring 8 7 4.5 cm; the leg soft tissue mass measured 10 8 6.6. cm, including tumor measuring 8 7 4 cm and the excised axillary soft tissue mass [cancerjournal.net]

Radiologic Findings A contrast-enhanced CT study showed a very well-defined, lobulated, heterogeneously enhancing soft tissue mass centered in the posterior nasal cavity, extending through the choanae into the nasopharynx. [ajnr.org]

Herein, this tumor is presented within a rare clinical setting, in a 45-year-old gentleman, with multiple soft tissue swellings and a previous history of surgical excision of a thigh mass. [cancerjournal.net]

Results of an x-ray of the right hand revealed soft tissue swelling over the second phalanx with no periosteal reaction. Results of a biopsy revealed a poorly marginated storiform spindle cell neoplasm involving the dermis and subcutaneous tissue. [mdedge.com]

Abstract A 48-year-old man of Haitian descent presented with progressive constipation, hematochezia, and weight loss. [ncbi.nlm.nih.gov]

There was no associated lymphadenopathy or hepatosplenomegaly. The patient was negative for neurofibromatosis (NF) status. [ijpmonline.org]

The latter finding was confirmed both histopathologically and immunohistochemically to have exactly the same appearances of the original dermal and subcutaneous mass. [ncbi.nlm.nih.gov]

Extraneural Soft tissue Perineurioma : (Including a conventional form) This is the common type and presents as a painless subcutaneous mass on the limbs or trunk of middle aged adults. 2. Intraneural Perineurioma: Rare type of lesion. [histopathology-india.net]

The patient was initially treated with marginal excision of the subcutaneous mass at a local clinic. Pathologic examination at that time suggested a soft tissue perineurioma with borderline malignancy. [healio.com]
