A hemangioma in the masseter muscle: a case report

Intramuscular hemangiomas of the masseter muscle are uncommon tumors and therefore can be difficult to accurately diagnose preoperatively, due to the unfamiliar presentation and deep location in the lateral face. A case of intramuscular hemangioma of the masseter muscle in a 66-yearold woman is presented. Doppler ultrasonography showed a 34× 15 mm hypoechoic and hypervascular soft tissue mass in the left masseter muscle, suggesting hemangioma. The mass was excised via a lateral cervical incision near the posterior border of the mandibular ramus. The surgical wound healed well without complications.

Intramuscular hemangiomas are unique vascular tumors which are benign in nature, most commonly occurring in the trunk and extremities. When present in head and neck, they most frequently involve the masseter and trapezius muscles, accounting for less than 1% of all hemangiomas. Most of these lesions present with pain and discomfort and some patients may demonstrate progressive enlargement. Due to their infrequency, deep location, and unfamiliar presentation, these lesions are seldom correctly diagnosed clinically. Our report is a clinically misdiagnosed case of a painful soft tissue mass in the right side masseteric region of a 23-year-old female patient, confirmed as intramuscular hemangioma based on imaging studies and histopathologic examination, treated by surgical excision which had no recurrence after a 3-year followup.

Epithelioid angiosarcoma (EA) is a subtype of angiosarcoma which is a rare tumor of endothelial origin. Here, we report a case of 15-year-old boy who presented with soft tissue mass lesion in the parotid region mimicking as a benign parotid tumor. Cytology was suggestive of inflammatory swelling. Patient underwent superficial parotidectomy along with the wide excision of the swelling. On histopathology, it was diagnosed as EA. To the best of our knowledge this is the first case report of epithelioid angiosarcoma of the masseter.

ABSTRACT Intramuscular hemangiomas are rare benign congenital neoplasms of vascular origin. They account for less than 1% of all hemangiomas and less than 20% of these are found in head and neck and present in 2nd and 3rd decade. The masseter is the most frequently involved site in the head and neck. Because of their infrequency, deep location and unfamiliar presentation, these lesions are seldom correctly diagnosed clinically and usually present as facial swelling causing facial asymmetry. A case of intramuscular hemangioma occurring in masseter muscle of an 8-year-old girl is presented here. Ultrasonography, color Doppler and Gd-enhanced MRI were performed and a presumptive diagnosis of hemangioma was considered which was subsequently confirmed by excision biopsy.

Intramuscular Hemangioma

A case was presented in which a 28-year-old male presented with tenderness and stiffness in the posterior muscle group of his right leg. The patient's symptoms had been present intermittently for nearly 23 years. Recently, the pain had progressed to the point of limiting his normal daily activities. Initial conservative therapy, which consisted of Zorprin, heel lifts, and low Dye strapping, failed to alleviate the symptoms. Magnetic resonance imaging was used to identify a mass of an unknown etiology. Following orthopedic and oncologic consultation, surgical excision was advised and performed. Pathologic examination of the mass confirmed that the tumor was an intramuscular hemangioma. Classically, with intramuscular hemangiomas, patients may have soft tissue complaints, such as pain and swelling, present for years. Patients usually defer medical attention until the primary symptom of pain occurs. When a patient complains of a painful soft tissue mass of the leg, and intramuscular hemangioma should be included in the differential diagnosis. The appropriate radiographic studies and consultations should be performed, and surgical excision should be carried out.

Intramuscular Hemangioma

Soft-tissue tumors in the foot include a range of benign and malignant pathologies. In the clinical setting, the list of differential diagnoses can be exhausting, and the treatment plan is not always straightforward. In this article, we present a case of a 22-year-old female with a soft-tissue mass on her plantar foot that has been slowly growing since adolescence and is now causing increased pain with ambulation. Her pathology results demonstrated an intramuscular hemangioma. Intramuscular hemangiomas are rare benign tumors that tend to present in youth or early adulthood. Diagnosis is often delayed for months to years, depending on the patient's symptoms. Treatment varies from conservative to surgical, depending on size, location, and proximity to vital structures. Literature on intramuscular hemangiomas is very limited. Intramuscular hemangiomas provide a diagnostic and treatment quandary for the clinician and must be considered in the differential diagnoses when presented with a soft-tissue mass.

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.

AbstractThe aim of this report is to describe an unusual localization of nerve sheath tumour (NST), clinical presentation, imaging, surgical management, and outcome in a 2-year-old dog. A 2-year-old female American Staffordshire Terrier presented with nonambulatory paraparesis, thoracolumbar hyperaesthesia, hindlimb hyperreflexia, and mild muscle atrophy. Computed tomography and magnetic resonance imaging revealed an extradural mass at T7-T8, without vertebral lesions. Surgical treatment consisted in resection of the soft tissue mass through dorsal laminectomy. The dog was ambulatory within 24 hours and free of recurrence at 18 months postoperatively. Histopathologic and features of immunohistochemistry were consistent with NST. The NST of this report was similar to those described before, but exhibited unusual characteristics, such as being extradural, without extension into intervertebral foramina, and being located in an atypical region (T7-T8). Moreover, survival time and relapse-free interval are greater than previously reported for similar cases.

Neo Adjuvant Chemotherapy

Synovial sarcomas are most commonly localised in extremities, especially in the lower thigh and knee areas. Comprising less than 1% of all malignancies, retroperitoneal synovial sarcoma is very rare with primary synovial sarcoma of the kidney being even more infrequent and difficult to diagnose. We describe a case report of a renal synovial sarcoma in a young adult who was initially managed as a case of Wunderlich’s syndrome secondary to what was believed to be a ruptured renal angiomyolipoma. After biopsy confirmation, the patient was eventually managed with neo-adjuvant chemotherapy followed by a right radical nephrectomy and right hepatectomy. Despite its rarity, synovial sarcoma should be considered as differential diagnosis of a bleeding retroperitoneal soft tissue mass detected in young adults.
