Nerilemmoma is well encapsulated tumour,which forms a single, round or fusiform firm mass on the course of a nerve.They arise from Schwann cells of neurilemma of nerves. These tumors often grow to a large size without causing any neurologic deficit.We report here a case of neurilemmoma of parotid gland showing histopathological findings of cellular neurilemmoma,in a 20 year old male patient.

Schwannomas are benign encapsulated nerve sheath neoplasm arising from differentiated Schwann cells. Herewith we present a case in a 32 years-old male patient presented with complaint of swelling on right lateral margin of tongue, since. The swelling was gradually increasing in size. On clinical examination lesion was 3.0 x 2.5x 1.5 cm. It was firm in consistency, smooth, mobile and non-tender on palpation. The overlying mucosa was normal. The excision of the mass was done with adequate surgical margins of resection. On histopathological examination reported as Schwannoma of tongue. We are presenting this case for its rarity, clinical, radioimaging, and histopathological findings. Key words: Nerve tumors, Schwannomas, Tumors of oral cavity.

We report a case of an unusual presentation of American Tegumentary Leishmaniasis involving a male patient with a solitary lesion on the ear lobe, persisting with minimal increase for at least six months without ulceration or related symptoms. The histological sections showed epithelial atrophy and a large number of structures consistent with Leishmania sp. amastigotes within macrophages. Treatment commenced with meglumine antimoniate resulting in regression of the condition. This report is of importance given the unusual clinical manifestation and histopathological findings in this case and the fact that there was low correlation with the extended duration of the disease.

ABSTRACT Cavernous hemangiomas are relatively rare vascular malformations especially in an adult. The childhood hemangioma generally regresses spontaneously. We present the case report of a 52-year-old male patient, who had a hemangioma from the childhood and it had grown to such a large size so as to cause extreme cosmetic deformity for the patient. The long standing duration of almost 45 years and the extremely large size of the hemangioma make it a very rare case. How to cite this article Gupta N, Verma H.

ABSTRACT Schwannomas are benign slow-growing encapsulated tumors arising from the Schwann cells that ensheath the axons of the peripheral, cranial, and autonomic nervous systems. About 25 to 45% of all Schwannomas are seen in the head and neck but Schwannoma of the external auditory canal is rare. We report a case of Schwannoma of the external auditory canal in a 18-year-old male patient. How to cite this article Kumar D, Somavanshi S, Kumar H, Agrawal A, Singh H.

AbstractA case of renal carcinoma metastatic to the left parotid gland is presented. A 60-year-old male patient developed a painful mass in his left parotid region one and a half years after he had undergone a left nephrectomy operation for renal carcinoma. The mass was excised surgically. The histopathological diagnosis was metastatic renal carcinoma. From a review of the literature, it is apparent that unlike most of the cases reported, this one had a very aggressive nature. The clinical presentation of the metastasis, and the factors determining the prognosis in cases of metastatic renal carcinoma to the head and neck are discussed.

Rare Case Report

The teeth are subjected to considerable variation for the number, size, form and structure of dental tissues. In this rare case report, a 30-year-old male patient was referred for root canal treatment of his right maxillary first molar because of deep caries in this tooth. During radiographic examination for determining the working length of this tooth, the peri-apical radiographs revealed the unfamiliar size of the maxillary first molar, in addition to severe curvature in mesiobuccal root. To achieve a successful treatment instrumentation of the canals completed with a crown-down technique, and obturation was done with lateral condensation technique.

AbstractMalignant oncocytomas are extremely rare tumours of the salivary glands. Fewer than 50 cases have been reported in the world literature so far, 34 of which were located in the parotid gland. Only three of these tumours have been located in the submandibular gland. We report one further case of a malignant oncocytoma of the submandibular gland in a 47-year-old man. Since a definite histological diagnosis of malignant oncocytoma can rarely be made both clinical and histopathological findings are essential in establishing the diagnosis. Treatment consists of wide surgical excision, neck dissection and post-operative radiotherapy. The prognosis with regard to five-year survival is poor becauseof metastatic disease.

Central Mucoepidermoid Carcinoma

ABSTRACT Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor, comprising about 15% of all salivary gland tumors and 30% of all salivary malignancies. Most of the MEC arise in the parotid gland. Rarely, it originates in the mandible and maxilla as an intraosseous variant, referred to as ‘central mucoepidermoid carcinoma’ or ‘intraosseous mucoepidermoid carcinoma’. Central mucoepidermoid carcinomas (CMECs) are extremely rare, but well-known entity, comprising 2 to 3% of all MECs reported. Histopathologically, this malignant neoplasm is characterized by mucous, intermediate and epidermoid cells. In this report, we present a case of a male patient diagnosed as low grade CMEC.
