A 35-year-old man with a complaint of right scrotal swelling was referred to our hospital. He had received testicular sperm extraction several times due to azoospermia. He received a high orchiectomy, and the pathological findings showed the tumor was pure seminoma. From the normal testicular tissue, sperm cells were extracted. Intracytoplasmic sperm injection was performed but the fertilization was not accomplished. Source

Background: The long-term prognosis of patients with acute myocardial infarction (AMI) in the contemporary acute revascularization era is not fully understood. Methods: To clarify long-term prognosis and prognostic factors of AMI patients in a real-world setting, we consecutively registered 3021 patients with AMI (mean age 69 years, 70.7% male) who were admitted to 17 participating medical institutions and followed up prospectively. The outcome measure was death from any cause. Results: Among 3021 patients, 629 patients had non-ST elevation MI (non-STEMI). During the index hospitalization, coronary angioplasty and thrombolytic therapy were performed in 58.1% and 16.3% of patients, respectively. During hospitalization, 285 patients (9.4%) died. Among 2736 patients (90.6%) who were discharged alive and followed for a median of 4.3 years (follow-up rate, 97.1%), 434 patients (15.9%) died. Among them, 250 (57.6%) died from non-cardiac causes. Compared with STEMI patients, non-STEMI patients suffered significantly more adverse outcomes. Advanced age and non-STEMI disease were associated with poorer outcomes. Multivariate analysis revealed that diabetes mellitus, acute-phase heart failure (Killip functional class ≥ 2), higher serum creatinine level (≥ 1.2 mg/dl), and advanced age (≥ 70 years and ≥ 80 years) at the onset of the AMI were independent poor prognostic factors (hazard ratios, 1.07, 2.53, 1.89, 2.50, and 6.80 respectively). Conclusions: AMI patients in the era of acute revascularization have favorable long-term prognoses, and a large proportion of late deaths are non-cardiac in nature. The establishment of an optimal management strategy for elderly AMI patients, AMI patients with diabetes, and non-ST elevation AMI patients are essential. © 2011 Elsevier Ireland Ltd.

The patient was a 53-year-old woman in whom ultrasonography of the breast revealed a lobular mass, 14 mm in diameter, in the right AB region. Spindle cells were obtained on fine-needle aspiration biopsy, but it was not possible to diagnose whether the tumor was benign or malignant. Contrast-enhanced magnetic resonance imaging showed a mass with a cystic component that was darkly stained in the early phase. Needle biopsy showed a dense proliferation of atypical spindle cells with no distinct epithelial-like arrangement. The differential diagnosis included mesenchymal malignant tumors such as fibrosarcoma, some phyllodes tumors, and epithelial tumors with sarcomatoid differentiation. Immunostaining revealed that the tumor was cytokeratin (AE1/AE3)-negative, partially CAM 5.2-positive, p63-positive, S100-negative, SMA-positive, partially vimentin-positive, with a Ki-67 index of 80% and negativity for ER, PgR, and HER2. Spindle-cell carcinoma was thus diagnosed. A partial right mastectomy with sentinel lymph-node biopsy was performed. Immunostaining of the resected specimen confirmed spindle cell carcinoma. The General Rules for Clinical and Pathological Recording of Breast Cancer classify spindle cell carcinoma as a special type of invasive cancer with a sarcomatoid structure, consisting of spindle-shaped cancer cells. This type of carcinoma is extremely rare, accounting for less than 1% of all breast cancers. Source

The patient was a 43-year-old single woman. Her family history included schizophrenia in her mother and manic-depression in her father. Remicade® (infliximab) had been administered for 3 years to treat rheumatoid arthritis. The patient initially Presented to our hospital with dyspnea. Computed tomography revealed left-sided breast cancer associated with multiple bone tumors and multiple pulmonary nodules. A poorly mobile mass with an ulcer was found in left breast. Core-needle biopsy and fluorescent in situ hybridization (FISH) revealed an invasive ductal carcinoma that was positive for estrogen and Progesterone receptors and human epidermal growth factor receptor 2 (HER2, 2+). The clinical diagnosis was Stage IV T4bN3M1 cancer (metastases to the lungs, liver, and bone). Because of the presence of bone metastasis, the patient was admitted and she received complete bed rest as supportive therapy. However, the patient decided to receive treatment on an outpatient basis after carefully discussing the following points: 1) treatment of pulmonary metastasis with dyspnea should receive priority; 2) anticancer agents not causing nausea were required; 3) the risk of bone fractures as a complication (spinal cord injury); 4) how she wanted to spend the limited time available with her family; and 5) how the patient wanted to.
