Male Veteran

We present a case of a 59-year-old male veteran with a chronic history of right foot soft-tissue mass that was causing pain in his shoes, but not functional or neurologic symptoms. Excision of the mass and pathologic evaluation resulted in multidisciplinary involvement and evaluation. In this example, the mass was found to be either an unusual schwannoma that happens to be psammoma body–rich or an unusual psammomatous melanocytic schwannoma that deviates from conventional examples, as a diagnostic consensus was unable to be reached. Schwannomas are an uncommon finding in the foot, and even more uncommon are those that contain psammoma bodies. Although rare, these tumors can be concerning for more systemic, life-altering diseases such as Carney complex, for which our patient refused genetic testing.

Abstract.Donnellan R, Moodley M. Vulval myxoid liposarcoma.A 26 year old woman presented with a 4-year history of a gradually enlarging fluctuant mass on the left labium majus. Histologic examination following excision revealed myxoid liposarcoma. Following the diagnosis, further surgery was performed to ensure complete resection. Routine excision of draining lymph nodes is not advocated. Although rare, myxoid liposarcoma should be considered in the differential diagnosis of a vulval soft tissue mass.

Incidental soft tissue lumps in the scalp are a common presenting complaint in clinical practice. However, they may signify more sinister underlying pathologies. Our report examines a 63-year-old man presenting with impaired co-ordination in his left hand following a 3-month history of a painless left retroauricular scalp lump. MRI revealed a large left occipital soft tissue mass eroding through the underlying skull with infiltration into the underlying cerebellum and temporal lobe. Open biopsy confirmed a diagnosis of high-grade intracranial neuroendocrine tumour (NET). At approximately 5 months following successful tumour resection and adjuvant chemotherapy, he developed tumour recurrence and was subsequently palliated, and died at 1 year post diagnosis. Herein, we review other cases of primary intracranial NET, clinical findings, histopathological features and prognosis.

Sarcoidosis of the parathyroid gland is a rare occurrence. Parathyroid sarcoidosis is usually associated with parathyroid adenomas, and, therefore, hypercalcaemia is a common presentation of this entity. We present a case of parathyroid sarcoidosis and review the world literature regarding this rare condition. A woman with a history of diffuse large B cell lymphoma underwent a surveillance positron emission tomography scan that showed increased fluorodeoxyglucose uptake in multiple thoracic and abdominal lymph nodes and in a left upper extremity soft tissue mass. Biopsy of the soft tissue mass showed non-caseating granulomas consistent with sarcoidosis. Blood work showed a serum calcium of 11.1 mg/dL with an intact serum parathyroid hormone of 92 pg/dL. Primary hyperparathyroidism was suspected. A neck ultrasound and sestamibi parathyroid scintigraphy demonstrated a parathyroid nodule. She underwent surgical resection, and the histopathology revealed a parathyroid adenoma and non-caseating granulomata consistent with a diagnosis of sarcoidosis.

The Mean

A total of 329 patients with osteoblastoma were retrospectively reviewed from the archives of the Armed Forces Institute of Pathology, of which 41 (12.5%) presented with tumors in the foot and ankle. This was the third most common site of disease after the spine and femur. Overall, the mean age was 22.5 years, which was the same for the foot and ankle subset of patients; however, there was a significant male predominance in foot and ankle patients compared with the whole group. The majority of patients were skeletally mature (85.4%). Clinically, most patients presented with pain (97.2%), although one-third of the total related a history of antecedent trauma. The interval between the onset of symptoms and biopsy was 84 days (range, 0–572 days). Radiographically, the majority of lesions were in the hindfoot (N = 18; 44%) of which 16 of 18 tumors (89%) were in the talus. Of these, one-half were subperiosteal and dorsally based and were associated with osseous tumor matrix and a soft tissue mass. Two osteoblastomas, both in the metatarsals, transitioned into sarcomas; the rest were histologically benign. For diagnostic purposes, it was essential to obtain clinical, radiographic, and histologic correlation.

Small blue round cell tumors of childhood rarely present in the foot or ankle. The following is a case presentation of an 18-year-old male with a large soft-tissue mass of the foot with associated lung metastasis. A definitive diagnosis could not be fully made, even with immunohistochemical and genetic testing. Diagnosis favored poorly differentiated synovial sarcoma.

Rheumatoid nodule1, one of the most characteristic manifestations of rheumatoid arthritis (RA), occurs in approximately 30% of patients, is generally associated with positive rheumatoid factor, smoking, and high disease activity2, and occurs in some patients with specific genotypes receiving methotrexate (MTX)3. An 83-year-old woman with a history of anticitrullinated protein antibody–positive RA treated by oral MTX, as well as gout, was hospitalized for a growing tumor of her right forearm.

Initial Imaging

Retroperitoneal fibrosis is a rare inflammatory disorder causing increased fibrotic deposition in the retroperitoneum, often leading to ureteral obstruction. We present a case report of a 33-year-old male with 2-month history of back pain. Initial imaging showed thickening around the infrarenal aorta. Six months later the patient presented with renal failure; a CT abdomen revealed extensive soft tissue mass around the aorta resulting in ureteral obstruction. Histology results of biopsy of the soft tissue mass revealed retroperitoneal fibrosis. It is important for clinicians to treat periaortitis early as this can prevent progression to retroperitoneal fibrosis which can cause severe secondary complications such as renal failure from ureteral obstruction.

A 7 yr old castrated male standard poodle weighing 25 kg was presented with a 5 day history of hematuria, dysuria, and the presence of a 2.5 cm, firm swelling within the prepuce. Abdominal radiographs revealed a soft-tissue mass on the distal prepuce and lysis of the cranial margin of the os penis. The patient was sedated and an ulcerated hemorrhagic mass was identified at the tip of the penis. The mass was diagnosed as hemangiosarcoma via incisional biopsy. A penile amputation with scrotal urethrostomy was performed followed by chemotherapy with doxorubicin.

We report a case of an unusual and unsuspected chronic infection creating a soft-tissue mass in the foot of a 35-year-old woman. The causative agent, Mycobacterium gordonae, is usually encountered as a laboratory contaminant. Only rarely does it manifest as a clinical infection. The patient’s presumed predisposing risk factor was a history of barefoot gardening. An iatrogenic source, corticosteroid injections, was also considered.
