Gastric Mucormycosis Masquerading as Gastric Malignancy.

Mucormycosis is an opportunistic fungal infection usually seen in immunocompromised patients. We report a case of gastric mucormycosis in an immune-competent lady that mimicked a gastric malignancy, presenting a diagnostic challenge. A high index of suspicion is required for the diagnosis and successful treatment of this potentially life-threatening condition.

The diagnostic and therapeutic challenges in the management of a double giant parathyroid adenoma.

Primary hyperparathyroidism is a common endocrine disorder of the parathyroid gland. It is mostly seen as a single gland adenoma in up to 85% of the cases with the excess production of parathyroid hormone. Double adenomas although reported are very rare and double giant parathyroid adenomas are even rarer.

A Rare Case of a Recurrent Giant Solitary Fibrous Tumor of the Ciliary Body of the Orbit.

Solitary fibrous tumors (SFTs) are uncommon spindle-cell tumors of mesenchymal origin initially described in the pleura and subsequently in other extra-pleural sites. These tumors are categorized as tumors of 'intermediate malignancy' under the World Health Organization classification of soft tissue tumors. SFT was virtually non-existent or misdiagnosed until its characteristic features, particularly the strong and diffuse immuno-reactivity to CD 34 were described.

A Rare Case of Multiloculated Cervical Thymic Cyst Masquerading as Tuberculous Adenitis.

Cervical thymic cysts are among the rarest cysts found in the neck. They usually occur during infancy and childhood, and they are extremely rare in adults. They may be found at any level of the pathway of normal thymic descent, from the angle of the mandible to the superior mediastinum.

Nodular Fasciitis of the Orofacial Region: An Uncommon Differential.

Nodular fasciitis is a benign proliferative spindle-cell lesion that presents as a rapidly growing mass arising from the subcutaneous fascia, leading it to be erroneously diagnosed as a sarcoma. These lesions commonly present in individuals in their third to fifth decades of life with no definite gender predilection. They are frequently located on the extremities and the trunk and infrequently in the head and neck region.

Metastatic Follicular Carcinoma Thyroid Masquerading as a Primary Jaw Tumor.

Metastatic tumours of the oral cavity are rare constituting approximately one percent of all oral malignancies. These tumors are clinically significant as their appearance may be the first indication of an undiscovered malignancy at a distant primary site or the first evidence of dissemination from a known primary tumor. Thyroid cancer metastasizing to the jaw bones is a rare occurrence and very few cases have been described in literature.

Dumbbell Shaped Schwannoma of the Lateral Chest Wall masquandering as a soft tissue sarcoma.

Schwannomas are benign, slow growing nerve sheath tumours of Schwann cell origin. They predominantly are known to involve the head, neck and the flexor surfaces of the extremities, retroperitoneum and the posterior spinal roots. The chest wall is a relatively uncommon location for a schwannoma, the vast majority of which are intra-thoracic, which are usually located in the posterior mediastinum and bulge into the thoracic cavity.

Role of fluorine-18-fluorodeoxyglucose positron emission tomography-computed tomography in management of pulmonary mucoepidermoid carcinomas and review of literature.

Pulmonary mucoepidermoid carcinoma (PMEC) is a rare tumor of bronchial gland origin with a striking resemblance to MEC of the salivary glands. The World Health Organization classifies PMECs as "salivary gland type" tumors along with pulmonary adenoid cystic carcinomas and epimyoepithelial lung carcinomas. Their description in literature is largely limited to a few case series/case reports.

Malignant chondroid syringoma of the pinna.

Chondroid syringoma (CS) represents the cutaneous counterpart of mixed tumor (pleomorphic adenoma) of salivary glands. The malignant counterpart of CS, termed as "malignant CS" is a malignant eccrine neoplasm which lacks distinctive clinical features, often delaying initial diagnosis. Unlike its benign counterpart which often localizes in the head and neck region, malignant CS most often encountered in the trunk and the extremities.

Diagnostic dilemma involving a mass in the parapharyngeal space: A metastatic breast carcinoma masquerading as a malignant salivary gland tumor.

Parapharyngeal space (PPS) tumors are rare and account for about 0.5% of all head and neck neoplasms. Most PPS tumors are benign (up to 80%) while the remaining 20% are malignant.

Clear cell odontogenic carcinoma of the mandible and temporomandibuar joint with cervical lymph nodal metastasis.

Clear cell odontogenic carcinoma (CCOC) is a rare aggressive tumor that has the ability to invade locally as well as cause regional and distant metastasis. The etiology of this neoplasm remains poorly understood and the diagnosis of CCOC is done by exclusion of other clear cell tumors. To date, approximately 75 cases of CCOC have been described in the English literature, all involving a single jaw.

Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography in the detection of primary pulmonary angiosarcomas.

Angiosarcoma is a malignant vascular tumor that originates from the mesenchymal cells which have undergone angioblastic differentiation. Pulmonary angiosarcomas are invariably (>90%) metastatic tumors form primaries of the skin, bone, liver, breast, or heart. Primary pulmonary angiosarcomas are exceedingly rare, with just about 20 cases being reported in the literature.

Multiple synchronous verrucous carcinomas of the scalp in the background of generalized verruca vulgaris.

Verrucous carcinoma (VC) is a clinicopathologic entity which is defined as a locally aggressive, clinically exophytic, slow-growing, well-differentiated, squamous cell carcinoma with negligible metastatic potential. The cutaneous form of VC is typically known to arise from the palmoplantar and the genitocrural areas. Involvement of the scalp is extremely rare.

A large extra cranial cystic trigeminal schwannoma of the parapharyngeal space - exploring the right approach.

Tumors of the parapharyngeal space (PPS) are uncommon, comprising less than 1 % of all head and neck neoplasm's. Neurogenic lesions are the most common tumors of the poststyloid PPS accounting for nearly 25-30 % of all the PPS lesions. Schwannomas are uncommon nerve sheath tumors that may originate from any peripheral, cranial or autonomic nerve of the body, about one-third of them are known to arise in the head and neck region.

Palliative thyroidectomy in the setting of a metastatic renal cell carcinoma.

A secondary neoplasm of the thyroid gland is a distinctly uncommon cause of thyroid enlargement. These tumors mimic primary thyroid gland tumors and often lead to diagnostic difficulties. We report an interesting case of secondary thyroid tumor coexisting with a micropapillary carcinoma in an elderly male patient following a radical nephrectomy done 15 years prior for a renal cell carcinoma (RCC).

Primary plasma cell leukaemia with unusual presentations: a case series.

We present here three cases of plasma cell dyscrasias; first case presenting as primary plasma cell leukemia showing unusual morphology and aberrant expression of myeloid markers; the second case presenting as plasma cell leukaemia with atypical plasma cells in peripheral blood and the third case presenting as myelomatous pleural effusion after treatment for myeloma.

The aesthetic and oncological challenges in the management of an atypical nodular hidradenoma of the pinna.

Nodular hidradenomas are benign adenomatous tumours of sweat gland origin, which commonly arise from the skin of the head, neck and extremities. Some of these benign appearing lesions exhibit aggressive clinical behaviour with rapid growth, pigmentation and ulceration. These tumors are designated as "atypical nodular hidradenomas" and are known to histologically possess some focal atypical features i.

Adult acute lymphoblastic leukemia mimicking renal cell carcinoma with wide spread bone metastasis.

A few cases with bilateral renal enlargement in acute lymphoblastic leukemia (ALL) are reported in literature. In this article, we report an unusual case of ALL in an adult presenting as multiple lesions in both kidneys and multiple bone lesions.
