Primary osteosarcoma of the uterus (uOS) is rare, and its standard treatment has not yet been established. Herein, we present the case of a 50-year-old woman with uOS who demonstrated an improved prognosis after multiple surgeries to the metastatic sites. After the initial diagnosis of uOS, the patient showed recurrence and distant metastasis and hence expected to exhibit a poor prognosis. The patient underwent multiple surgical resections of the metastatic as well as primary tumors, which enabled the patient to survive for 24 months after the initial surgery. Considering that the median survival time of patients with uOS is approximately 6 months, the survival rate of our patient is noteworthy. Based on our observations, it is suggested that the resection of the primary and metastatic tumors might contribute to the extension of the survival period of the patient with chemo-resistant uOS.

Chronic expanding hematoma (CEH) is defined as chronic hematoma enlargement for more than 1 month. Although CEH rarely occurs on the floor of the mouth, the need to distinguish these cases from malignant disease is critical, given the need for potentially extensive resection in patients with malignancy. We report a case of CEH on the floor of the mouth, which required differentiation from malignant tumor. A 42-year-old woman was referred to our hospital for a submucosal mass on the right floor of the mouth, with a diagnosis of class 3 on aspiration cytology. Computed tomography revealed a submucosal mass with peripheral calcification on the floor of the mouth, which exhibited a hypointense rim on T2-weighted imaging and gradual nodular-like enhancement in the periphery on contrast-enhanced magnetic resonance imaging. Enucleation was performed to reach a definitive diagnosis, and CEH was confirmed pathologically. Well-defined morphology, presence of calcification, a hypointense rim on T2-weighted imaging, and weak peripheral nodular-like enhancement may be characteristic findings of CEH on the floor of the mouth. Accordingly, these imaging features may aid in differentiating CEH from low-grade malignancies and in determining the optimal management strategy.

Hepatic granuloma is relatively rare, and benign tumor of the liver. Herein, we report an unusual case of hepatic granuloma mimicking intrahepatic cholangiocarcinoma (ICC). An 82-year-old woman with a history of viral hepatitis B was admitted for investigation of liver mass in the left lobe. Dynamic computed tomography revealed a mostly hypo-enhancing main tumor with a peripheral ring enhancement, and positron emission tomography demonstrated localized an abnormal accumulation of fludeoxyglucose. Considering the possibility of malignant disease, extended left hepatectomy was performed. The resected tumor was macroscopically a periductal infiltrating nodular type, 4.5 × 3.6 cm in diameter. The pathological findings showed that granuloma and coagulative necrosis were present, and diagnosis of hepatic granuloma was confirmed. Pathological studies demonstrated that periodic acid-Schiff stain, Grocott-Gomori stain and Ziehl-Neelsen stain were all negative in the lesion.

Among testicular neoplasms, ovarian-type epithelial tumors constitute an exceedingly rare group, with only a few cases reported in the literature. We describe the case of an 82-year-old man, presented with complaints of right leg pain and difficulty walking, who was found to have a large right tibial metastasis of unknown primary origin. Whole body CT scan did not reveal any cranial, thoracic or abdominal tumor masses, but it showed abnormal para-aortic lymph nodes and right spermatic cord swelling. An extemporary ultrasound examination found a right testicular mass. The patient underwent radical orchiectomy, and the diagnosis of a serous papillary carcinoma of the ovarian epithelial type of the testis was made. To the best of our knowledge, this is the first case in the literature of isolated bone metastasis from ovarian-type epithelial tumor of testis.

Brain metastases from bladder cancer are rare, with a poor prognosis. There is no standard treatment for bladder cancer with brain metastases; thus, palliative therapy is generally provided. We report a case of abscopal effect in a single brain metastasis from bladder cancer in a patient treated with focal stereotactic radiotherapy (total dose = 52 Gy, administered in eight fractions) with immune checkpoint blockade therapy for lung metastases, who achieved long-term disease-free survival (> 4 years). To our knowledge, although there have been some reports on abscopal effects in bladder cancer, there are no previous reports on patients with brain metastases. To date, the brain metastasis, which showed an "abscopal effect," continues to maintain complete regression.

An 80-year-old man with an approximately 3-cm mass in the right submandibular region presented to our institution. Magnetic resonance imaging revealed enlarged lymph nodes (LNs) in the right neck, and fluorine-18-2-deoxy-D-glucose (FDG) positron emission tomography (PET)/computed tomography (CT) indicated positive FDG accumulation in the right neck LNs only. Excisional biopsy was performed for suspected malignant lymphoma, and the biopsy revealed melanoma. Close examination of the skin, nasal cavity, oral pharyngeal and laryngeal cavities, and gastrointestinal tract were performed. No primary tumor was detected by these examinations, and the patient was diagnosed with cervical LN metastasis from melanoma of unknown primary of clinical stage T0N3bM0 stage IIIC. The patient refused cervical neck dissection because of his age and comorbidity of Alzheimer's disease and instead opted for proton beam therapy (PBT) at a total dose of 69 Gy (relative biological effectiveness) in 23 fractions. He did not receive any systemic therapy. The enlarged LNs shrunk slowly, and FDG PET/CT at 1 year after PBT showed that the right submandibular LN had shrunk from 27 to 7 mm in length, and there was no significant FDG accumulation. At 6 years and 4 months after PBT, the patient is alive without any recurrence.

We report a rare case of peritoneal and pulmonary tuberculosis after intravesical instillation of Bacillus Calmette-Guérin (BCG). A 76-year-old man diagnosed as high-grade urothelial carcinoma (UC) with carcinoma in situ (CIS) was treated with intravesical BCG instillation and transurethral resection of bladder tumor (TUR-BT). Three months later, TUR-BT for recurrent tumors and multiple site biopsy of bladder mucosa were performed. During TUR-BT, near perforation in the posterior wall was observed, and was disappeared after observation with urethral catheterization for 1 week. Two weeks later, he was admitted with a complaint of abdominal distention, and a computed tomography (CT) showed ascites. One week later, CT showed pleural effusion and worsening of ascites. Drainage of pleural effusion and ascites puncture was performed, and elevated adenosine deaminase (ADA) and lymphocytes count were subsequently found. In laparoscopic examination, numerous white nodules were observed in the peritoneum and omentum, and Langhans giant cells were pathologically identified in biopsy specimens. Mycobacterium culture confirmed Mycobacterium tuberculosis complex. The patient was then diagnosed with pulmonary and peritoneal tuberculosis. Anti-tuberculous agents consisting of isoniazid (INH), rifampicin (RFP), and ethambutol (EB) were administered. Six months later, a CT scan showed no evidence of pleural effusion or ascites. There has been no recurrence of either urothelial cancer or tuberculosis during follow-up for 2 years.

A 54-year-old man was diagnosed with descending colon cancer with metastases in the liver, para-aortic lymph nodes, and penis, and chemotherapy was introduced after construction of a colostomy. The patient reported only mild penile pain at the time of diagnosis; however, the pain gradually worsened and interfered with his daily life. Opioids did not provide sufficient analgesia, and the patient developed dysuria and priapism. Through construction of a cystostomy, palliative radiotherapy with QUAD Shot regimen (14 Gy in 4 fractions twice-daily on 2 days repeated every 4 weeks) to the penile metastasis was started for pain relief and tumor shrinkage. The radiation rapidly improved the penile symptoms, enabling opioid reduction and cystostomy removal. The patient remained pain-free and able to urinate on his own until his death. Metastatic penile tumors are rare, especially those derived from colon cancer. Penile metastases occur mainly in the late stages of cancer and may impair the patient's quality of life. In such cases, palliative radiotherapy, especially with QUAD Shot regimen, is useful with short treatment time, durable symptom control, and little adverse effect, maintaining quality of life.

Extraovarian adult granulosa cell tumor is a very uncommon neoplasm, which probably arises from the ectopic gonadal tissue along the embryonic root of the genital ridge. We report a new and rare case of an extraovarian adult granulosa cell tumor occurring in a 66-year-old woman who was presented with severe abdominal pain focused on the left iliac fossa. The immunohistopathology confirmed the diagnosis of a paratubal adult granulosa cell tumor. This paper illustrates the histogenetic origin of granulosa cell tumor, its clinicopathological and immunohistochemical features.

After a 75-year-old man was diagnosed with lung cancer, proximal weakness and myalgia in the bilateral lower extremities developed, and the creatinine kinase (CK) level was elevated. The anti-Mi-2 antibody test was positive, muscle T2-weighted/fat-suppressed magnetic resonance imaging showed high intensity, and there were no skin lesions. Therefore, he was diagnosed with lung cancer-associated polymyositis (PM). The lung tumour shrank after chemotherapy, accompanied by gradual improvement of his PM-derived symptoms and CK level. Although positive anti-Mi-2 antibody tests rarely indicate PM and cancer, examining myositis-specific autoantibodies, including anti-Mi-2, should be considered if the CK level increases after a cancer diagnosis.
