Introduction. Lipomas are the most common benign mesenchymal tumors, which account for almost 50% of all soft-tissue tumors. Case Outline. The case of a 75-year-old patient with a slow growing lesion of para- and retropharyngeal space was reported. The patient was suffering from progressive dysphagia, respiratory obstruction and sleep apnea. Conclusion. An external surgical approach is the treatment of choice. Etiology, differential diagnosis and therapy of head and neck lipomas has been discussed.

A case of clear cell hidradenoma occurring on the medial aspect of the first metatarsophalangeal joint of the right foot was presented. Common clinical data and histologic presentation were discussed. Although an infrequent tumor of the foot, this tumor should be included in a differential diagnosis of soft tissue tumors.

Pharyngeal injuries caused by trauma are common and have been reported previously in the medical literature. In some cases of a penetrating injury there is a collection of air in the retropharyngeal space that can be shown on lateral soft tissue radiography of the neck. If this condition is not diagnosed or adequately treated the patient may develop severe complications such as mediastinitis. A case is reported of a patient with penetrating injury caused by a pencil and the subsequent treatment with review literature are described.

AbstractMyoepithelial neoplasms of soft tissue are rare tumors with clinical, morphological, immunohistochemical, and genetic heterogeneity. The morphological spectrum of these tumors is broad, and the diagnosis often requires immunostaining to confirm myoepithelial differentiation. Rarely, tumors show a morphology that is typical for myoepithelial neoplasms, while the immunophenotype fails to confirm myoepithelial differentiation. For such lesions, the term “myoepithelioma-like” tumor was introduced. Recently, two cases of myoepithelioma-like tumors of the hands and one case of the foot were described with previously never reported OGT-FOXO gene fusions. Here, we report a 50-year-old woman, with a myoepithelial-like tumor localized in the soft tissue of the forearm and carrying a OGT-FOXO1 fusion gene. Our findings extend the spectrum of mesenchymal tumors involving members of the FOXO family of transcription factors and point to the existence of a family of soft tissue tumors that carry the gene fusion of the OGT-FOXO family.

Schwannomas are generally slow growing asymptomatic neoplasms that rarely occur in the GI tract. However, if found, the most common site is the stomach. Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and 60–70% of them occur in the stomach. Owing to their typical presentation as submucosal neoplasms, gastric schwannomas and GISTs appear grossly similar. Accordingly, the differential diagnosis for a gastric submucosal mass should include gastric schwannomas. Furthermore, GI schwannomas are benign neoplasms with excellent prognosis after surgical resection, whereas 10–30% of GISTs have malignant behavior. Hence, it is important to distinguish gastric schwannomas from GISTs to make an accurate diagnosis to optimally guide treatment options. Nevertheless, owing to the paucity of gastric schwannomas, the index of suspicion for this diagnosis is low. We report a rare case of gastric schwannoma in 53-year-old woman who underwent laparoscopic partial gastrectomy under the suspicion of a GIST preoperatively but confirmed to have a gastric schwannoma postoperatively. This case underscores the importance of including gastric schwannomas in the differential diagnosis when preoperative imaging studies reveal a submucosal, exophytic gastric mass. For a gastric schwannoma, complete margin negative surgical resection is the curative treatment of choice.

ABSTRACT Shwannoma, better known as neurilemmomas, are benign, slow growing, usually solitary and encapsulated tumor, originating from Schwann cells of the nerve sheath. They are exceedingly rare in the base of tongue and, therefore, not immediately thought of as a differential diagnosis of oropharyngeal tumors. However, the key to the diagnosis lies in the histopathologic examination. A number of surgical approaches have been proposed for tongue base Schwannomas with varying degree of postoperative morbidity. We report a case where a 19-year-old woman presented to us with progressive dysphagia, occasional dysarthria, and was found to have a large tongue base lesion. Diagnosis was confirmed by imaging studies and biopsy. Transoral laser assisted excision of the tumor was done. Histologic identification of Antoni A and B areas along with strong and diffuse staining with S-100 stain confirmed the diagnosis of Schwannoma.

Scapular Region

Introduction: Winging of scapula is defined as a failure of dynamic stabilizing structures that anchor the scapula to the chest wall, leading to prominence of the medial border of scapula. It could be primary, secondary, or voluntary. Primary winging could be true winging due to neuromuscular causes or pseudo-winging due to osseous or soft-tissue masses. A scapular osteochondroma is a very rare presentation site and causes pseudo-winging leading to pushing away of the scapula away from the chest wall presenting as medial border prominence. Here, we are reporting a rare case of a scapular osteochondroma causing a pseudo-winging of the scapula. Case Report: A 2-year-old male child presented with painless, immobile, and non-fluctuant swelling over the left scapular region, insidious in onset and progressive in nature. On examination, a non-tender, immobile swelling was palpable with a painless and unrestricted range of motion at the shoulder joint. After evaluating radiographs and CT scan, the patient was diagnosed to have a ventral scapular osteochondroma leading to pseudo-winging of the scapula. Conclusion: Despite the rarity, a differential diagnosis of a scapular osteochondroma should be kept in mind while examining a young child presenting with a winged scapula. Keywords: Scapula, osteochondroma, pseudo-winging.

We report a case of multiple myoepithelioma with synchronous bone and soft tissue tumors, associated with a new genomic alteration of the LPP locus. The lesions occurred in the foot by presenting one lump in the plantar soft tissue, and three lesions were detected in the calcaneus and in the navicular bone. All tumors showed the double immunophenotype of epithelial markers and S100 protein expression. No rearrangement of the EWSR1 and FUS loci was detected as reported in myoepitheliomas. However, molecular karyotyping detected an unbalanced rearrangement of the LPP locus, not involving the HMGA2 locus, which is the most frequent translocation partner observed in benign mesenchymal tumors such as lipomas (of soft tissue as well as parosteal) and pulmonary chondroid hamartoma.

Lipomas are benign soft tissue neoplasm which rarely occur in the oral cavity. Of the total reported cases of lipoma, only about 15% to 20% of cases have occurred in the head and neck region and the tongue is an even rarer site with only about 4% of the reported cases occurring in that region. They are slow growing and usually asymptomatic in nature. When it grows to a large size, it can hinder the physiological processes that are associated with the area. This case report describes the diagnostic features of tongue lipoma with a brief review of literature.
