This report describes a rare case of nodular fasciitis (NF) of the oral cavity, discussing the clinical, histological, and immunohistochemical characteristics. Histopathologic diagnosis of this type of lesion can be challenging due to its differential diagnosis, which principally includes sarcoma. The patient presented with a painless, well-defined nodule, reported as increasing in size, located at the apical aspect of the upper left buccal sulcus. Histologically, the lesion revealed spindle cell proliferation arranged in fascicles, while immunohistochemistry demonstrated positivity for smooth muscle actin. Eight months after complete surgical excision, no signs of local recurrence have been observed.

Abstract Benign fibroblastic polyps of the colon are a recently described entity among mucosal polyps found in the colorectum. These polyps are typically discovered on routine screening colonoscopy within the distal colon. Benign fibroblastic polyps occur most commonly in adult women in the sixth decade of life. Histologically, benign fibroblastic polyps are bland spindle cell lesions that fill the lamina propria and displace the surrounding crypts. The spindle cell proliferation lacks atypia and significant mitotic activity. Hyperplastic changes are frequently present both in the adjacent epithelium and within the lesions. Immunohistochemically, the cells of benign fibroblastic polyps are invariably positive for vimentin with rare focal positivity for CD34 and smooth muscle actin. They are negative for CD117 and S100 protein. Ultrastructurally, benign fibroblastic polyps have features of fibroblastic differentiation. These polyps are benign with no reports, to our knowledge, of recurrence or metastasis.

Complete Surgical Excision

In each of seven ferrets ( Mustela putorius furo) with leiomyosarcoma, a single dermal mass was identified and biopsied. Each mass consisted of a well-demarcated but nonencapsulated proliferation of large spindle- to strap-shaped cells arranged in interwoven bundles. The cells resembled the smooth muscle cells of the adjacent arrector pili muscles, but with marked nuclear pleomorphism. Immunohistochemical staining for smooth muscle actin, desmin, and vimentin was positive and staining for myoglobin and cytokeratin was negative. Follow-up on three of the ferrets indicates that the prognosis is good following complete surgical excision.

The term ‘liposarcoma’ refers to a spectrum of neoplastic lesions that can be benign to malignant and likely to recur or metastasize. Liposarcoma is a common soft tissue sarcoma found in adults and occurs mostly in extremities especially thigh followed by retroperitoneum. Here we present a case of spindle cell variant of well differentiated liposarcoma of mesorectum and underwent Anterior resection for the same. The treatment of choice for liposarcomas of retroperitoneum remains debatable and there are no clear-cut guidelines available regarding the same. However, considering the higher rates of local recurrence we advise a complete surgical excision following anatomical principles.

In Pregnancy

Solitary nerve sheath tumor such as Benign schwannomas arising in the pelvic retro peritoneum is infrequently reported. Retroperitoneal location accounts for 0.3-3.2% of primary schwannomas. We report a case of benign retroperitoneal pelvic schwannoma in pregnancy that was incidentally diagnosed when it presented with Preterm premature rupture of membranes and mechanical obstruction for labour. She underwent caesarean section and delivered a healthy baby. She was evaluated in the postoperative period by computerized tomography (CT) imaging studies and CT guided fine needle aspiration cytology (FNAC) was not diagnostic. Complete surgical excision of the tumor was achieved in the postpartum period. The adjacent vascular and urinary channels sustained no injuries and she had no neurologic deficit. Histology revealed spindle cell neoplasm composed of interlacing fascicles and sheets of spindle cell with focal areas of nuclear palisading and thick walled blood vessels. Immunohistochemistry was positive for S 100 suggesting schwannoma. Retroperitoneal location of schwannomas is rare and surgery is curative. Prognosis is good, since recurrence is rare.

<p class="abstract">Schwannoma are slow growing tumours, which can arise from any peripheral nerve. 10% of schwannomas that occur in the head and neck region mostly originate from the vagus or sympathetic nervous system. Extracranial schwannomas in the head and neck region are rare neoplasm. Intraoral schwannoma are only 1% of the all head and neck tumours. Diagnosis is established by imaging studies such as magnetic resonance imaging or computed tomography, while FNAC is used to rule out other conditions. We report a rare case of lingual schwannomas generally present as a painless lump schwannoma of the tongue in a 27-year-old male complaining of asymptomatic swelling over a posterolateral surface of the tongue, treated by complete surgical excision. The diagnosis was established on the basis of clinical, histopathological, and immunohistochemical examination. We report a rare case of schwannoma over the posterolateral surface of tongue. Prognosis is good for the patient when this condition is correctly diagnosed as the condition rarely recurs after complete resection.</p>

Herein we report a rare case of a giant myopericytoma presenting in a 16-year-old girl as a slowly progressive swelling involving the scalp in the occipital region. It was managed by complete excision. Histological examination of the lesion revealed  spindle-shaped cells forming characteristic rosettes around the blood vessels, and positive staining with smooth muscle actin.

We report a case of myopericytoma of the neck. A 23-year-old woman noticed a small, nontender mass in her left supraclavicular fossa. The mass had grown over a period of 5 months, prompting her to seek evaluation. On examination, no motor or sensory deficits were present. Imaging suggested that a mass had originated in the middle scalene muscle. Computed-tomography–guided core needle biopsy demonstrated a spindle-cell neoplasm with smooth-muscle differentiation. Complete surgical excision was performed. Histopathologic and immunohistochemical evaluations of the tissue sample suggested a myopericytoma. Myopericytoma is an extremely rare tumor of the head and neck. To the best of our knowledge, this is the first reported case of a myopericytoma originating in a scalene muscle.
