Schwannomas or neurilemmomas are slow-growing, benign and often firm lumps that are typically painless. They are extremely rare in the oral cavity, with the tongue and the palate being the most common intraoral sites. This is a case report of this pathology in the floor of the mouth. We present a case of a 28-year-old female patient with a 2-month history of a floor of mouth swelling. On clinical examination this was non-tender and appeared firm. An ultrasound of the lesion was performed which revealed a well-defined, rounded and low reflective soft tissue mass. Following an MRI scan and surgical excision of the lesion, a definitive diagnosis of a schwannoma was made. The presence of schwannoma in the oral cavity is unusual. Based on the literature and the presented case, it should be considered as a differential diagnosis until the final histopathological confirmation.

Case summary A 7-year old male neutered domestic shorthair cat was presented with a 2 month history of a slow-growing mass on the right zygomatic area. A CT scan revealed a soft tissue mass in the right zygomatic region with no alterations of the underlying bone and features of local invasiveness. Cytology was suggestive of a mesenchymal tumour and histopathology from an incisional biopsy was consistent with a soft tissue sarcoma (STS). The cat was treated with neoadjuvant intravenous doxorubicin chemotherapy at a dose of 25 mg/m2, every two weeks. The patient experienced a partial response and underwent surgical excision of the tumour. Doxorubicin was continued as an adjuvant treatment for three further chemotherapy sessions, at a dose of 25 mg/m2 every 21 days. Local tumour recurrence was detected on clinical examination and cytologically confirmed 259 days following surgery. Relevance and novel information Treatment with neoadjuvant doxorubicin can be considered in cases of inoperable STSs in order to cytoreduce the tumour and improve the chances of achieving complete surgical margins. The role of adjuvant chemotherapy in this setting remains unclear.

This article describes a patient with plantar fascial pain who presented to the office of one of the authors. Physical examination and the patient’s description of the history of symptoms revealed classic signs and symptoms of plantar fasciitis. The patient was treated with numerous conservative modalities, including ultrasound, nonsteroidal anti-inflammatory medications, trigger-point injections, over-the-counter orthoses, and stretching exercises. When the pain was not relieved by these conservative measures, magnetic resonance imaging of the area was performed. Visualization of the insertional area of the plantar fascia revealed a mass inferior to, as well as infiltrated into, the plantar fascia. Surgical excision of the lesion resulted in complete elimination of the patient’s pain. (J Am Podiatr Med Assoc 91(2): 89-92, 2001)

A 7-y-old backyard Leghorn chicken ( Gallus domesticus) was submitted to the California Animal Health and Food Safety Laboratory System (CAHFS)–Turlock branch for postmortem examination, with a history of unexpected death. At postmortem examination, a hemorrhagic soft tissue mass was observed in the cervical region. Microscopically, a densely cellular neoplasm of polygonal epithelial cells and small lymphocytes was observed. The microscopic features of the neoplasm in combination with positive immunohistochemistry for pancytokeratin and CD3 were used to classify the lesion as a thymoma. Thymoma was diagnosed in only 5 birds submitted to CAHFS from 1990 to 2019. Thymoma has been described only rarely in birds, and is an unusual diagnosis in backyard chickens.

Fibroma of tendon sheath (FTS) is an uncommonly encountered soft tissue mass, which is morphologically distinct from the more commonly seen giant cell tumor of tendon sheath (GCTTS). Initially described in 1936, FTS is typically a slow growing, painless, firm mass with a predilection for the upper extremity, frequently involving the hand. Cases of associated triggering or compression neuropathies have been described when underlying tendons or nerves are affected. Currently, the literature on FTS is sparse and largely limited to case reports. More recently, few reports of cytogenetic analysis on FTS have been reported in the literature. Cellular and chromosomal analysis of FTS tissue revealed chromosomal translocations with yet unknown clinical significance. Here, we present a case report of FTS in a 14-year-old male with a painless enlarging mass on the palmar side of the left hand treated by excision. Subsequent karyotypic analysis revealed a chromosomal translocation t(4;10) (p16;q24), add (10)(q22)[24]. To our knowledge, this is the first description of this chromosomal aberration in the literature.

Background. Conventional osteochondromas are common bone lesions developing in the metaphyseal region of growing skeleton. Marginal excision is the treatment of choice for such tumours. Extraosseous cartilaginous tumours are rare and their biological potential is poorly characterized.Case Presentation. A-52-year old woman presented with 3-year history of fullness and dull pain and inability to flex her left knee, sit cross-legged, or squat. Clinical and imaging studies revealed a nodular mineralised mass in the anterior portion of the knee displacing the patellar tendon laterally. Excision biopsy confirmed the diagnosis of extraosseous osteochondroma-like soft tissue mass. There is no recurrence at two-year followup.Conclusion. An integrated clinicopathological diagnosis helps to clarify the nature of extraosseous cartilaginous tumour that can arise at an unusual anatomic site. Complete surgical excision is the treatment of choice.

AbstractBackground:Dermoid cysts in the floor of the mouth are relatively uncommon developmental lesions. They are thought to arise in the midline and along the lines of embryonic fusion of the facial processes containing ectodermal tissue.Case report:A 17-year-old female presented with a 3-month history of a growing, progressive swelling in the mouth floor. Clinical examination revealed a rather large symmetrical, soft swelling in the mouth floor, displacing the tongue superiorly. The fast growing nature and size of the lesion raised suspicion of potential compromise to the airway. Surgical excision was therefore performed.Conclusion:Differential diagnosis of cystic lesions in the floor of the mouth is of paramount importance, as the recommended surgical techniques vary depending on the anatomical position of the lesions. The intraoral approach is preferred for those lesions that do not extend beyond the mylohyoid muscle boundaries; this leads to a satisfactory cosmetic and functional outcome.

We report the rare case of a histologically proven mixed-type intramuscular haemangioma, adjacent to the periosteum of the radius, that caused a periosteal reaction. We also carried out a review of the literature relevant to this case. A 28-year-old male professional drummer presented with an 8-month history of pain and swelling of the dorsal aspect of the right radius. Diagnosis was established on the basis of plain radiographs and magnetic resonance imaging, and was confirmed by histology. The lesion was treated solely by resection of the soft-tissue mass. The patient remained asymptomatic 4 years post-operatively, with no radiographic signs of recurrence. From a review of the literature, it is evident that the terminology for haemangiomas causing regional bone changes is unclear. A new classification of the intramuscular haemangiomas is proposed in order to distinguish between lesions that, according to current knowledge, exhibit radiological and clinical areas of overlap.

Atypical Localization

Musculoskeletal system is rarely involved by hydatid cyst, the larvalform of Echinococcus granulosus. Two cases of intramuscular hydatid cysts within thigh musculature are being reported with the intent of highlighting this atypical localization of the disease. Preoperative computerized tomography suggested an unusual location of echinococcus. Since the soft tissue tumors may be confused with hydatid cysts, preoperative evaluation of these patients is critical for proper handling during surgery to avoid life-threatening complications. Surgical excision with postoperative antihelmenthics formed the main modality. These cases emphasize that especially in endemic areas to avoid fine-needle biopsy and the risk of spillage of cyst contents hydatidosis should be included in differential diagnosis of any soft tissue mass.
