The rapid improvement in visual field defect observed with weekly perimetry during intensity-modulated radiotherapy for optic nerve sheath meningioma

During precision radiotherapy to treat optic nerve sheath meningioma, early improvement in visual function has been seen. This has been difficult to explain biologically. In the present study, we aimed to investigate this rapid improvement in visual function. To this end, we prospectively tested a single patient’s visual field (VF) using Humphrey automated perimetry at weekly...

Small-cell lung carcinoma with ovarian metastasis 4 years after the first-line treatment

Small-cell lung carcinoma rarely metastasizes to the ovary. Only few cases of this condition have been reported to date. A 42-year-old female nonsmoker was an outpatient after receiving treatment for small-cell lung carcinoma. Approximately 45 months after the first-line treatment, the pro-gastrin-releasing peptide level exhibited a gradual increase. Positron emission tomography...

A case of angiosarcomas which occurred in an adrenal gland and spleen synchronously

We report a case of a 56-year-old woman who simultaneously presented adrenal and spleen tumors. Computed tomography imaging revealed a 7-cm enhancing adrenal and 2-cm solitary spleen masses. The patient simultaneously underwent left adrenalectomy and splenectomy. The pathological findings revealed the presence of synchronous adrenal and spleen angiosarcomas. Remarkably, she is...

Pyoderma gangrenosum after radical prostatectomy: case report

Pyoderma gangrenosum (PG) is a skin disease characterized by an unknown neutrophilic infiltration in dermis and a nonbacterial destructive ulcer. Post-operative PG is an extremely rare type that occurs around surgical sites during the immediate post-operative period. It is usually diagnosed as surgical site infection at the time of presentation. The condition rapidly worsens...

Successful radiotherapy for endometrial serous carcinoma with local repeated recurrence

The incidence of endometrial serous carcinoma (ESC) has been increasing, and ESC is resistant to treatment. We report a patient with ESC who responded to radiotherapy for multiple recurrences. The first recurrence was detected in the vaginal wall and left internal iliac lymph node 5 months after the initial treatment. Concurrent chemoradiotherapy (CCRT) was administered...

A case of mature cystic teratoma with intestinal structures harboring intestinal-type low-grade mucinous neoplasm

The formation of gastrointestinal-type epithelium is found in 7–13% of mature cystic teratomas, which are the most common germ cell tumors of the ovary. Few cases harboring organized gastrointestinal tract formation have been reported, and a mucinous neoplasm arising in them is further rare. Here, we report a case of an ovarian mature cystic teratoma with intestinal structures...

Extramedullary plasmacytoma of the ureter in an HIV-positive patient

A 45-year-old Japanese man, who was undergoing HIV infection treatment, was aware that he had gross hematuria, and he was diagnosed as having a ureteral tumor by radiographic examination. Therefore, he was referred to our department for further examination and treatment. We considered that the ureteral tumor was a urothelial carcinoma (cT2N0M0) because of the left ureteral tumor...

Pseudomyxoma peritonei due to low-grade appendiceal mucinous neoplasm with symptoms of inguinal hernia and uterine prolapse: a case report and review of the literature

Pseudomyxoma peritonei (PMP) is an unusual condition in which massive amounts of mucinous ascites in conjunction with mucinous peritoneal and omental implants occur. We herein report a case of PMP due to low-grade appendiceal neoplasm (LAMN) and a literature review to clarify the clinical features of PMP. A 68-year-old female suffered from anorexia and abdominal distension and...

A case of gastric metastasis from renal cell cancer during the sequential targeted therapy

Historically, gastric metastasis from renal cell cancer (RCC) has been extremely rare. As RCC is now being treated with various agents of targeted therapy, however, the rate of unusual visceral metastases might increase as outcomes improve and follow-up periods grow longer. Here we present a valuable case of gastric metastasis from RCC detected in a routine CT scan during...

Transanal approach for intersphincteric resection of rectal cancer in a patient with a huge prostatic hypertrophy

The gold standard of surgical technique for rectal cancer is total mesorectal excision (TME). Laparoscopic TME has been proven to provide surgical safety and oncological outcomes equivalent to open TME. However, dissection of the lower rectum has some inherent difficulties related to a narrow pelvic space. The challenge of TME in the lower rectum was confirmed by the Colorectal...

Possible de novo clear cell carcinoma in the contralateral ovary 9 years after fertility-sparing surgery for Stage IA clear cell ovarian carcinoma

A patient who underwent fertility-sparing surgery for Stage IA clear cell carcinoma may have developed de novo clear cell carcinoma in the contralateral ovary 9 years later. She underwent fertility-sparing surgery and postoperative adjuvant chemotherapy for right ovarian carcinoma at 33 years of age (when endometriosis was observed in the contralateral ovary). At the age of 41...

Successful conservative management of diffuse cavernous hemangioma of the rectum

Diffuse cavernous hemangioma of the rectum (DCHR) is a relatively rare disease. A 40-year-old man presented with long-standing lower abdominal discomfort and hematuria. At the time of hospitalization, his vital signs and hemoglobin level were normal. Colonoscopy showed markedly dilated blood vessels in the sigmoid mucosa, which was confirmed on magnetic resonance imaging and...

A case report of using nivolumab for a malignant melanoma patient with rheumatoid arthritis

The use of antibodies against programmed cell death 1 (PD-1), which block inhibitory T cell checkpoints, is a promising new therapy for advanced malignant melanoma and NSCLC. However, patients with autoimmune diseases were excluded at the clinical trial using such immune checkpoint inhibitor, because of the possibilities to worsen an adverse event of the autoimmune disease. Thus...

Long-term combination chemotherapy using eribulin and trastuzumab for three patients with human epidermal growth factor receptor 2-positive metastatic breast cancer

The combination chemotherapy regimen of eribulin (ERI) and trastuzumab (TRA)—the ERI-TRA regimen—has been shown to be highly tolerable for patients with recurrent or metastatic human epidermal growth factor receptor 2 (HER2)-positive breast cancer. However, no sufficient clinical evidence is available for the long-term safety profile of the regimen. We report on three patients in...

Marked improvement in leptomeningeal carcinomatosis and spinal cord metastases following alectinib treatment of crizotinib-resistant, ALK-positive lung adenocarcinoma

We report a case of 50-year-old Japanese female with anaplastic lymphoma kinase (ALK)-positive, crizotinib-resistant lung adenocarcinoma, whose leptomeningeal carcinomatosis and spinal cord metastases were dramatically improved by the second-generation ALK inhibitor alectinib. Magnetic resonance imaging (MRI) revealed multiple brain metastases at diagnosis of lung cancer...

Huge polypoid endometriosis: report of a case and review of the literature

‘Polypoid endometriosis’ is a rare variant of endometriosis. We describe a case of an extremely large polypoid endometriosis mimicking a malignant tumor. A 37-year-old nulliparous woman was referred due to the rapid growth of an endometriotic cyst of the ovary and a high serum CA125 level. MRI revealed solid components in the pelvic mass. These preoperative clinical data were...

Metastatic mechanism of spermatic cord tumor from stomach cancer

Metastatic spermatic cord tumors are relatively rare, and gastric, colorectal, and pancreatic cancers have been reported as the primary lesion [1, 2]. We experienced a case of metastasis to the spermatic cord 1 year after surgery for gastric cancer. A 68-year-old male developed a painful right inguinal mass 1 year after surgery for gastric cancer and tubular adenocarcinoma was...

Peritoneal strumosis, 10 years after laparoscopic surgery for mature cystic teratoma of the ovary: a case report

Peritoneal strumosis, a condition in which benign thyroid tissue spreads to the peritoneal cavity, is extremely rare. Here we report the first case of peritoneal strumosis, 10 years after laparoscopic surgery for mature cystic teratoma of the ovary. A 64-year-old woman was referred to our hospital due to suspicion of a recurrence of rectal carcinoma in September 2011. Under the...

Efficacy and safety of gemcitabine monotherapy in an elderly patient with penile metastasis from bladder carcinoma: a case report

We describe the case of an 85-year-old Japanese male with invasive urothelial carcinoma of the bladder treated with radiotherapy and the significant effects of gemcitabine monotherapy on subsequent metastases to the lungs, L5 vertebral body, and penis. The lung and L5 vertebral body metastases were diagnosed 3 months after radiotherapy and were treated with one course of...

Pleural dissemination of gastric gastrointestinal stromal tumor (GIST): a rare type of recurrence found 11 years after curative resection

Extra-abdominal metastasis of gastrointestinal stromal tumor (GIST) is very rare. We herein report a case of pleural dissemination from gastric GIST found 11 years after curative resection. A 58-year-old Japanese man, who had undergone proximal gastrectomy for gastric GIST 11 years ago, visited our hospital complaining of dyspnea and tightness of the chest. Computed tomography...
