Incomplete Removal

Osteoid osteoma is a small, benign tumor usually of endochondral bone, affecting mainly the long bones of the extremities and occurring not uncommonly among children. It produces pain which may disturb sleep and interfere with normal activities. The roentgenogram reveals a radiolucent area surrounded by osteosclerosis. This is suggestive of osteoid osteoma but differential diagnosis from certain other neoplastic, inflammatory and metabolic lesions of bone must be made. Thirteen children with osteoid osteoma have been treated by excision of the lesion at the Mayo Clinic. The results have been uniform alleviation of symptoms. This experience and that obtained elsewhere has shown that incomplete removal of the nidus may lead to recurrence of the symptoms.

Sclerotic Bone

Osteoid osteoma is a benign tumor that accounts for roughly 10-12% of all benign bone forming tumors. This tumor generally occurs within the first three decades of life and occurs more commonly in males. This lesion is painful and is generally worse at night and has relief of symptoms with the use of NSAIDs. Osteoid osteoma is characterized by the production of osteoid surrounded by a rim of sclerotic bone. These lesions most commonly occur in long bones such as the proximal femur, however they can occur anywhere. Rarely, as with our patient, have these lesions been reported in the acetabulum.

Diagnostic Dilemma

Osteoid osteomas are well-known benign tumors, seen generally in long bones. When seen in phalanxes or toes, they can cause a diagnostic dilemma. A young male presented to us with complaints of enlargement of the great toe and severe pain. He had had an ingrown toe-nail operation before, and this situation caused a diagnostic dilemma. In this case report, we emphasize that osteoid osteomas can cause diagnostic dilemmas and it should be kept in mind as a differential diagnosis.

Histopathologic Evaluation

Osteoid osteoma is a benign tumor originating from osteoblasts, and it is mostly seen in long bones of lower limbs. The distal phalanx of the foot is an atypical location for an osteoid osteoma, and lesions occurring in this location may be a diagnostic challenge. A 22-year-old man presented with a complaint of severe pain on the second distal phalanx of his right foot. An osteoid osteoma was suspected after radiologic evaluation. The lesion was surgically excised and removed completely by curettage. Histopathologic evaluation confirmed the diagnosis of an osteoid osteoma. The patient was followed-up for a 9-month period without any symptoms or recurrence.

Gastric Mass

Gastric schwannomas are rare mesenchymal tumors that arise from the nerve plexus of gut wall. They present with nonspecific symptoms and are often detected incidentally. Preoperative investigation is not pathognomic and many are therefore misdiagnosed as gastrointestinal stromal tumors. We report a rare case of a 37-year old woman who underwent laparotomy for complex bilateral ovarian cyst with resection of gastric-gastrointestinal stromal tumor preoperatively, but confirmed to have a gastric schwannomas postoperatively. This case underscores the differential diagnosis of submucosal, exophytic gastric mass as schwannoma.

Background: PRMC is a very rare benign tumor of the abdominal cavity that usually occurs in women, and PRMC demonstrate no specific findings on CT. There are many reports on the differential diagnosis and discussion of PRMC imaging, but there are few reports on the treatment of dedifferentiated PRMC using laparoscopic resection and postoperative follow-up.

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.

An eight-year-old male neutered Jack Russell terrier presented with fever, shoulder and elbow pain and progressive right forelimb lameness. Haematology revealed a non-regenerative anaemia and marked thrombocytopenia. Radiography and CT of the thorax and abdomen revealed bilateral asymmetrical osteogenic-osteolytic changes to the scapulae, humeri, femurs, pelvis, ribs and vertebrae. Histopathology of the bone marrow of the left humerus confirmed a metastatic skeletal adenocarcinoma. This case features a presumptive manifestation of disseminated carcinomatosis of the bone marrow with a bilateral asymmetrical distribution in a metastatic adenocarcinoma of unknown primary origin. Disseminated carcinomatosis of the bone marrow should be included in the differential diagnosis with polyostotic osteolytic and osteogenic, bilateral asymmetrical lesions in the long bones, vertebrae, ribs and pelvis.

Extrarenal angiomyolipoma (AML) is an extremely uncommon lesion, accounting for less than 9% of all angiomyolipomas. We present a previously unreported case of a rarely located gigantic extrarenal angiomyolipoma at the posterolateral chest wall of a 35-year-old woman. Clinically, the lesion had all the characteristics of a benign tumor, being soft in palpation, painless, and growing in size in a slow rate. Histologically, the lesion consisted of convoluted thick-walled blood vessels without an elastic layer, interlacing fascicles of smooth muscle, and mature adipose tissue, features consistent with an angiomyolipoma. The mass was surgically removed, without any postoperative complications, and the patient has an uneventful postoperative course. Signs of local recurrence have not been observed. The purpose of this brief report is to point out the necessity of including angiomyolipoma in the differential diagnosis of adipose layer lesions.
