Introduction Schwannomas are benign tumors originating from differentiated Schwann cells. Being the least common intraoral neoplasm of neural origin, it is rarely seen in the palate. The literature lacks an extensive review of intraoral schwannoma confined to the palate. Objective To review previously reported cases of palatal schwannoma along with an illustrative case, and to provide a better insight regarding clinicopathological and radiological features of this neural tumor in a rare intraoral site. Data Synthesis We present a case of palatal schwannoma in a 16-year-old female. An additional 45 cases were identified in 2 medical database searches (PubMed and Google Scholar) published from the year 1985 onwards, and from 13 countries, in the 5 continents. The ages of the patients ranged from 3 to 84 years old. Palatal schwannoma showed a slight predilection to females, with a male/female ratio of ∼ 1:1.81. Hard palate involvement is almost twice greater than soft palate involvement. Surgical excision was employed in almost all of the cases, and recurrence was reported only once. Conclusion Palatal schwannomas, although rare, have been reported both over the hard and the soft palate. They mostly present as a painless, firm, well-encapsulated, slow-growing solitary lesion over the lateral palatal aspect.Imaging can add to suspicion and can delineate a differential diagnosis, but the diagnosis is confirmed by pathological examination. Fine-needle aspiration cytology (FNAC) is almost always inconclusive. Immunohistochemistry can assist in confirming a diagnosis, but is more important to rule out close differentials. Complete surgical excision is the treatment of choice, and recurrence or malignant transformation are extremely rare.

Retroperitoneal Schwannoma

Background and Objectives: Retroperitoneal schwannoma is a very rare case of schwannoma which commonly occurs in the other part of the body. However, it is difficult to distinguish schwannoma from other tumors before pathological examination because they do not show specific characteristics on imaging study such as ultrasound, computed tomography (CT), and magnetic resonance image (MRI). Case summary: A 60-year-old male showed a retroperitoneal cystic tumor which is found incidentally during evaluation of coexisted bladder tumor. Neurogenic tumor was suspicious for the retroperitoneal tumor through pre-operative imaging study. Finally, a schwannoma was diagnosed by immunohistochemical examination after complete surgical excision laparoscopically. Conclusion: As imaging technology is developed, there may be more chances to differentiate schwannoma from other neoplasm. However, still surgical resection and histopathological examination is feasible for diagnosis of schwannoma.

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.

Cervical Root

Cervical root schwannoma is an infrequent benign peripheral nerve tumor though those arising from high cervical spinal root are common amongst the spinal schwannomas. This mass commonly presents as a slow growing, asymptomatic, solitary neck mass with rare potential of   malignant degeneration. Displacement of Internal jugular vein and carotids anteriorly is frequently seen though abutment of esophagus is uncommon. Pre operative diagnosis can be established with imaging and Fine needle aspiration cytology (FNAC). Complete Surgical excision is the treatment of choice. Horner’s syndrome is the most common post operative neurological manifestation. Here we have recorded clinical features intra-operative findings and surgical histopathology. We have described a case of 19 year old male with cellular schwannoma of cervical sympathetic chain with intraspinal extension and arising from C5-C8 level. Another case of cervical root schwannoma is described in a 5 year old girl arising at C4-C5 level. Complete surgical excision was done for both patients with no postoperative neurological affection. The clinico-pathological evaluation and management are described

Giant Lipoma

Lipoma is the most common benign tumor of adipose tissue. Giant lipoma of breast is very rare.Majority of them are small in size, slow growing and asymptomatic until they reach large size. Most patients seek medical advice due to asymmetry in the breast and due to fear of malignancy. Breast lipomas pose a diagnostic challenge due to similarity of their texture to normal breast parenchyma and make it difficult to distinguish from other common breast lesions. The clinical and radiographic identification of breast lipoma remains challenging. Complete surgical excision with the capsule is essential to prevent recurrence. Breast reconstruction may require, to prevent asymmetry following surgical excision of giant breast lipoma. High degree of clinical suspicion and histolopathological correlation will help in preopertaive diagnosis of this clinical condition. Here, we report a case 50- year -old woman with left breast lump which clinically, radiologically and on fine needle aspiration cytology was diagnosed as phyllodes tumor, but after surgical excision it was reported as breast lipoma on final histopathology.

<p>Schwannomas are less common benign slow growing tumors originating from Schwann cells. In the head and neck region, schwannomas arise most commonly from the vagus nerve or the sympathetic chain. We present this case as the location of schwannoma is extremely rare and due to the diagnostic difficulties it posed. A 48 year old male presented with right neck swelling and breathing difficulty to our OPD. Patient underwent ultrasonogram of neck, MRI neck and Fine needle aspiration cytology (FNAC) of the lesion. Each of the investigations suggested different pathology which made the diagnosis challenging. During surgery, the lesion was found to arise from right recurrent laryngeal nerve. After excision of the lesion, the patient developed hoarse voice and the pathological examination revealed schwannoma. Schwannomas that originate from Schwann cells can affect any part of the body. MRI, CT, USG and FNAC have been suggested in the literature for diagnosing the lesion. Trucut biopsy should be considered in situations where FNAC becomes inconclusive. Surgical excision is the treatment of choice. Histologically, five variants of schwannomas have been described in the literature namely common, plexiform, cellular, epithelioid and ancient schwannoma. To conclude, schwannoma arising from RLN which masqueraded as a thyroid swelling is a rare entity. The diagnostic modalities suggested in the literature were unable to pin point the diagnosis. Once, FNAC shows an inadequate specimen, a trucut biopsy should be considered as the next investigation modality.</p>

Objectives: Pleomorphic adenomas are benign tumors that rarely involve nonsalivary glands. We report an uncommon case of ala nasi pleomorphic adenoma. We discuss the clinical and histopathologic characteristics, and review the literature on nasal pleomorphic adenoma. Method: A 20-year-old man presented with a painless slow growing lobulated mass located on the right ala nasi extending into the nasal vestibule. Results: Complete surgical excision was performed. Histologic examination found a mixed cellular component: epithelial and myoepithelial cells with chondromyxoid stroma. This was consistent with the diagnosis of a typical pleomorphic adenoma. There was no evidence of recurrence at 18 months after the surgery. Conclusions: Pleomorphic adenomas located in the external nose are extremely rare. In such case, pleomorphic adenoma could originate from ectopic minor salivary gland. Complete surgical excision with long-term follow-up is recommended due to the potential risk of recurrence and malignant transformation.

Objective: To describe a rare pathology, the liposarcoma of the spermatic cord (LSC), and discuss its diagnosis and treatment. Materials and Methods: We report a case of well-differentiated LSC in a 61-year-old man. The main complaint was painless enlargement in the right inguinoscrotal area that appeared 6 months prior to presentation. Ultrasonography showed a heterogeneous and hyperechogenic mass of the right spermatic cord that was highly suspicious of malignancy. Computed tomography confirmed a heterogeneous supratesticular mass. The mass was surgically removed. Results: Pathological examination showed a well-differentiated LSC. The patient did not receive any additional treatment. The follow-up did not present complications or further symptoms and, at present, the patient is in complete remission. Conclusion: LCSs are a very rare entity. The diagnosis is difficult and often mistaken with common scrotal swelling associated with a hernia, hydrocele, or other tumour. Treatment should include complete surgical excision, usually by radical inguinal orchiectomy. A long follow-up period is necessary.

Introduction: A dermoid cyst is a developmental choristoma lined with epithelium and filled with keratinized material arising from ectodermal rests pinched off at suture lines. These are the most common orbital tumors in childhood. They are categorized into superficial and deep. Superficial orbital dermoid tumors usually occur in the area of the lateral brow adjacent to the frontozygomatic suture. Infrequently a tumor may be encountered in the medial canthal area [1], which is the second most common site of orbital dermoids. We report a case where a swelling presented in the medial canthal area without involving the lacrimal system. Case report: A 43 year old lady presented with complaint of swelling near the (RE; Right eye) since 2 years duration. She presented with a solitary 1.5 cm x 1 cm ovoid, non-tender, non-pulsatile, firm, non-compressible mobile swelling with smooth surface over the medial canthus of right eye. (MRI; Magnetic Resonance Imaging) brain and orbit showed right periorbital extraconal lesion and the (FNAC; Fine Needle Aspiration Cytology) suggested of Dermoid Cyst. RE canthal dermoid cyst excision was done under Local Anasthesia. Conclusion: Complete surgical excision in to be treatment of choice for dermoids. Since medial canthal mass can involve the lacrimal system, it becomes necessary to perform preoperative assessments using (CT; Computed Tomography), MRI or dacryocystography while planning the surgical approach. Silicone intubation at the beginning of the surgery is an easy and effective way of identifying canaliculi and of preventing canalicular laceration during dermoid excision if the lacrimal system is found to be involved.

Abstract Solid-pseudopapillary neoplasm of the pancreas is a relatively uncommon tumor. It typically affects young women, has nonspecific clinical and radiologic manifestations, and can be readily diagnosed by ultrasound-guided fine-needle aspiration and histopathologic evaluation. Histologic features characteristically show loosely cohesive, relatively uniform polygonal cells surrounding delicate capillary-sized blood vessels. Other features include cytoplasmic vacuolization, finely stippled chromatin, nuclear grooving, eosinophilic hyaline globules, and degenerative changes. Almost all solid-pseudopapillary neoplasms harbor mutations in the β-catenin gene. They stain with β-catenin, CD10, and focally with neuroendocrine markers. Although previously considered benign, this tumor is currently considered a low-grade malignant epithelial neoplasm with low metastatic rate and high overall survival. Most patients are cured by complete surgical excision. Despite the characterization of the morphologic and molecular features of this enigmatic neoplasm, more work is needed to uncover its cell of origin and true histogenesis.
