Abstract Schwannomas are rare tumours arising from peripheral nerve sheath. Here, a 44-year-old lady came to our clinic with an asymptomatic progressively-enlarging swelling over her upper back. It was fluctuant, with an absence of pain and tenderness. MRI showed a benign, purely-cystic, superficial-intermuscular, extra-spinal swelling nearby upper thoracic vertebrae. Complete surgical excision proceeded smoothly through a well-defined plane between the swelling and the muscles. It was not attached to any identifiable nerve. A 6.5x5.0x2.5 cm ovoid lesion with a glistening whitish-grey capsule was excised and wound reconstructed in layers. Histopathology showed hypercellular areas with nuclear palisading or oval-shaped Verocay bodies. Only S-100 tested positive amongst the five-antigen immunohistochemistry, thus establishing the diagnosis of a schwannoma. Postoperatively, a one-year follow-up period was uneventful. Schwannomas can surprise clinicians by arising anywhere and with atypical presentations. It needs to be in the differential diagnoses of any asymptomatic slowly-growing lesion.

Abstract Schwannomas are rare tumours arising from peripheral nerve sheath and are usually related to the spinal cord and spinal nerves. Contrast magnetic resonance imaging (MRI) usually helps in establishing a pre-operative diagnosis. Rarely, their manifestation may be surprisingly new. Here, a 44-year-old lady came to our clinic with a painless asymptomatic progressively enlarging swelling over her upper back. It was fluctuant, with absent neural signs and symptoms. MRI showed a benign, purely-cystic, superficial-intermuscular, extra-spinal swelling near the upper thoracic vertebrae. However, classical diagnostic signs of schwannoma were absent. Complete surgical excision was performed with smooth dissection through a well-defined plane between the lesion and surrounding muscles. A 6.5x5.0x2.5 cm oval lesion with a glistening whitish-grey capsule was excised, and the deep wound was reconstructed in multiple layers. Interestingly, it was not attached to any identifiable nerves. Histopathology showed typical hallmarks like Antoni A regions and Verocay bodies. Positive S-100 staining during immunohistochemistry established its diagnosis as schwannoma. The postoperative one-and-half-year follow-up period was uneventful. Cystic schwannomas can surprise and confuse clinicians by arising anywhere in the body and with atypical manifestations. Surgeons need to consider it in the differential diagnoses of any undiagnosed slowly-growing swelling, including purely-cystic ones and perform careful surgical dissection to avoid any inadvertent nerve damage.

Background: Myxoma is a rare tumor most frequently discovered in cardiac locations. The present report describes a rare case of extracardiac origin in the femoral vein, initially presenting as leg pain and swelling. Case Presentation: A 40-year-old woman was admitted to our regional hospital with unilateral left leg swelling and pain. She underwent a Duplex scan and CT scan, which revealed a 21 x 25 mm diameter mass in contact with the distal femoral vein, initially diagnosed as a thrombosed sacciform aneurysm. The patient underwent surgical excision of a bulging mass in the vein wall, which was directly closed by running suture. The anatomopathological report concluded with a myxoma. One-year follow-up showed a patent vein without evidence of recurrence of the tumor. Conclusion: Although very rare, peripheral venous myxoma may manifest with common symptoms as leg pain and swelling. Current vascular imaging and complete surgical excision should be performed without delay to allow a precise diagnosis and prevent further complications.

Schwannomas are usually benign rare tumors that originating from Schwann cells of peripheral nerve sheaths. Presentation is generally varied and changed in a non-specific range from abdominal mass, flank pain to incidental findings. Herein we report 2 cases of retroperitoneal giant schwannomas with different clinical presentations, of whom one presented with vague abdominal pain, palpable abdominal mass for 4 years, swelling and bilateral hydronephrosis that caused by giant abdominal mass; the other one presented with right flank pain, rectal hemorrhage and lower extremities edema. Two patients were treated by complete surgical excision of masses. The histological and immunohistochemical diagnosis was reported as benign schwannoma. Both of patients are doing well and had no recurrence in 9 years and 28 months follow-up, respectively.

Melanotic neuroectodermal tumors of infancy (MNTIs) are rare fast-growing tumors with high recurrence rates. These tumors, which originate in the neural crest, commonly occur in the anterior maxilla of children under the age of one. Here, we describe an MNTI case in a two-month-old girl with increasing swelling in the left cheek. MNTI was diagnosed in this case following tomography and biopsy. The patient's histological and immunohistochemical profile indicated a remarkable combination of neural, melanocytic, and epithelial cell differentiation. One year following tumor excision, a follow-up examination revealed that the child exhibited no tumor recurrence. Approximately 260 cases of MNTI have been reported since this type of tumor was first described. In the present case, early diagnosis minimized the difficulties and risks associated with treatment and facilitated an optimal outcome. Despite complete surgical excision, careful followup is recommended. In addition, maxillary functional orthopedics and reconstruction may be necessary in cases of MNTI.

Introduction. Myoepithelioma primarily affects the parotid gland and usually presents as a slow-growing painless lump. The aim of this paper is to report a case of myoepithelioma in the mouth floor. Case outline. A young man noticed a painless increased volume in the left side of the mouth floor region, which after one year of evolution presented as a sessile tumor with normal colored mucosa and the absence of secretion output. Computed tomography with contrast showed an image with slightly heterogeneous density, with well-defined limits. Incisional biopsy was performed under local anesthesia, and pathology examination of the sample revealed a myoepithelial neoplasm. Total excision of the lesion was performed under general anesthesia, and histopathological examination confirmed the diagnosis of the salivary gland myoepithelioma. The patient did not present signs of relapse after a year of follow up. Conclusion. Despite the fact that myoepithelioma originating in the salivary gland are considered rare, especially in the mouth floor, this tumor should be considered in the differential diagnosis of similar lesions. Proper treatment appears to be complete surgical excision and post-operative follow-ups shows should be carried out as long as possible, despite the fact that relapses are extremely rare.

<b><i>Introduction:</i></b> Koenen tumors are benign, cutaneous manifestations of tuberous sclerosis. These are disfiguring, painful, and challenging to treat as they frequently recur. We report a case of long-standing, multiple Koenen tumors affecting all twenty nails in an elderly female who was successfully treated with a combination of topical sirolimus 1%, surgical excision, and electrofulguration. <b><i>Case Report:</i></b> A 57-year-old lady presented with multiple, asymptomatic periungual, and subungual tumors affecting all twenty nails since 27 years. Cutaneous examination revealed confetti macules, ash-leaf macule, and shagreen patch over trunk. Nail biopsy was compatible with Koenen’s tumor. Computerized tomography of brain showed diffuse patchy sclerosis. The tumors were treated with topical sirolimus 1% ointment for 10 months with excellent regression. Electro­fulguration for both great toenails and surgical excision of right thumbnail periungual fibroma was done. 1% sirolimus was advised after the surgical treatment. There were no adverse effects or recurrence of tumors over a 2-year follow-up. <b><i>Discussion:</i></b> Topical sirolimus 1% was effective in tumor regression and preventing new tumor formation. Larger tumors that interfered in daily chores were treated with excision and electrofulguration. Thus, a combination treatment for this rare presentation of tuberous sclerosis provided optimum results.

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.

Oral Soft Tissue

Lipomas are benign tumours of mesenchymal origin (mature adipocytes) that are comparatively uncommon in the oral cavity corresponding to less than 4.4% of all benign oral soft tissue tumors. Clinically, they present as slow growing, soft, asymptomatic masses. Histopathologically, they appear as thinly encapsulated lesion composed of mature adipocytes with inconspicuous vascularity. The pathogenetic mechanisms of oral lipomas are still unclear. They are usually treated by surgical excision and bear excellent prognosis. Here we report a case of intraoral lipoma in 54 year old male patient in the left lower lingual alveolar mucosal region that was treated by surgical excision using electrocautery without any postsurgical complication. One-year follow-up showed no evidence of recurrence.
