We describe a unique case of a sublingual-space schwannoma presenting as a painless, 3 × 2-cm enlarging mass in the oral cavity of a 63-year-old man. Computed tomography demonstrated a distinct, well-encapsulated mass in the right side of the floor of the mouth. Findings on fine-needle aspiration cytology were consistent with a pleomorphic adenoma. Transoral excision was performed. Intraoperatively, the mass appeared to involve the nerve to the mylohyoid muscle. Upon removal, the gross tumor measured 4.4 × 3.5 × 2.5 cm. On microscopic examination, the spindle-cell neoplasm was found to be consistent with a schwannoma. Schwannomas of the sublingual space are exceedingly rare. Moreover, to the best of our knowledge, this case represents the first published occurrence of a schwannoma that arose from the mylohyoid nerve.

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.

We describe a unique case of a cholangiocarcinoma that metastasized to a cervical lymph node—to our knowledge the only such case ever reported. The diagnosis was based on fine-needle aspiration cytology and confirmed by excision biopsy. This case illustrates the importance of keeping all possible options in mind when diagnosing head and neck masses.

ABSTRACTCutaneous myxomas are rare benign neoplasms which are frequently associated with Carney complex (CNC). Although more than 500 cases of CNC are reported, there is no literature on cytologic diagnosis of Cutaneous myxomas. An 18-year-old male, with no significant family history, presented with multiple cutaneous swellings, largest measuring 15 cm on the right cheek. He also had spotty skin pigmentations, raised adrenocorticotropic hormone levels and recurrent cardiac myxomas. Fine-needle aspiration cytology from the right cheek and suprapubic swellings revealed paucicellular smears with abundant myxoid material in the background, admixed with fragments of spindle and stellate cells with bland nuclear morphology, and vascular proliferation in few fragments. There was no mitosis, necrosis, or any epithelial element. Hence, diagnosis of cutaneous myxomas in CNC was made which was confirmed on histopathology. This is the first report of cytologic diagnosis of multiple cutaneous myxomas in CNC and the largest cutaneous myxoma reported in literature.
