Clinical Differential Diagnosis

Schwannoma is a tumor of schwann cell proliferation which presents as a solitary, soft, skin-colored dermal or subcutaneous papulo-nodule most commonly on the flexor part of extremities and head and neck areas. Here, we report a case of nail unit schwannoma, which is a rare tumor of the nail apparatus with only 4 other prior reports in the literature. This case illustrates the importance of including subungual schwannoma in the clinical differential diagnosis of subungual soft tissue tumors. We include a literature review which catalogs and summarizes the current knowledge regarding this unusual nail unit neoplasm.

Granular Cell Myoblastoma

The granular cell myoblastoma is a rare tumor of childhood with only 10 cases previously reported. The occurrence of the tumor in the vulva of a 6-year-old child is presented. No authentic case of this tumor in its malignant form has been recorded in childhood. The granular cell myoblastoma should be considered in the differential diagnosis of soft tissue tumors in children and offers an excellent prognosis.

Soft Tissue Swelling

Only 0.5 to 2% of hydatid cysts are localized in the skeleton and of these, 3 to 4% are found in the skull. In this paper, the authors report a case of primary hydatidosis involving the cranial vault revealed by a bulging mass of the forehead and symptoms of raised intracranial pressure that occurred in a 22-year-old woman who came from a rural area. Through this case and literature review, the authors analyse the epidemiological, clinical and radiological aspects of skull hydatidosis. They conclude that hydatid cyst should be considered in the differential diagnosis of any soft tissue swelling or osteolytic lesion in the scalp of patients living in endemic areas.

Important Differential Diagnosis

An osseous choristoma is a benign tumor consisting of regular bone tissue in an irregular localization. Choristomas in the head and neck region are rare. Most frequently, they are found in the region of the tongue or oral mucosa. There are also very few reports on osseous choristomas in the submandibular region. We present the case of a woman with a large, caudal osseous choristoma within the lateral cervical triangle. Literature review is given about all of the reported cases in the region of the neck. The pathogenesis is yet unexplained. Our case supports the theory that the development of an osseous choristoma is a reaction to a former trauma. Cervical osseous choristomas are seldom, but they represent an important differential diagnosis when dealing with a cervical tumor.

Neurogenic Tumors

Neurogenic tumors are an uncommon yet important category of soft tissue tumors in children and adolescents because of their frequent association with various genetic syndromes. The heterogeneous cellular composition of the peripheral nerve and the wide metaplastic capacity of the neural crest and its derivatives generate a variety of neoplasms with neurogenic differentiation. This article reviews the clinicopathologic features and differential diagnosis of neurogenic tumors in the first two decades of life, and highlights use of selected ancillary methods for diagnosis.

Context Immunohistochemistry is a useful tool for diagnosing salivary gland and head and neck tumors. Objective To review immunohistochemical markers, which can aid in the diagnosis of selected salivary gland and head and neck tumors. Data Sources Literature review and authors' personal practice experience. Conclusions Salivary gland and head and neck tumors include a large diverse group of tumors with complex and overlapping histologic features. Immunohistochemistry plays an important role in resolving the differential diagnosis of some salivary gland and head and neck tumors and can provide information for the prognosis of certain tumors.
