Delayed and Synchronous Recurrence of Breast Cancer Metastases in Multiple Organs: A Case Report.
The most common sites of breast cancer metastasis include the lymph nodes, bones, lungs, liver, and brain. Gastrointestinal tract metastasis is rarely seen, and hypopharyngeal metastasis is extremely rare. We herein report a case of late distant recurrence of breast cancer and synchronous metastasis to the hypopharynx, stomach, ileum, bones, and lymph nodes almost 24 years after surgery. To our knowledge, this is the first case of synchronous metastasis to the hypopharynx, gastrointestinal tract, and other organs, especially after a long interval following primary mastectomy.

Objective Currently, treatment of relapsed or refractory multiple myeloma is challenging. Although bortezomib-thalidomide-dexamethasone-cisplatin-doxorubicin-cyclophosphamide-etoposide (VTD-PACE), a potent combination of a proteasome inhibitor, immunomodulatory drug, and conventional chemotherapeutics, is a widely used regimen, its efficacy and safety are unclear. Methods We retrospectively analyzed the clinical data of 35 patients treated with VTD-PACE. ⋯ The response and survival durations were short in patients without SCT after VTD-PACE [median PFS: 4.0 (95% CI, 2.7-5.3) months; OS: 14.0 (6.9-21.0) months]; however, these responses significantly improved with SCT following VTD-PACE. The PFS was 8.0 (NA) months (p=0.024), and the OS was 21.0 (19.1-22.8) months (p=0.019). Conclusion VTD-PACE is an effective and tolerable salvage regimen and feasible bridging therapy for SCT.

Sudden Cardiac Arrest due to Spontaneous Coronary Artery Rupture - A Case Report with a Diagnostic Challenge.
Spontaneous coronary artery rupture (SCAR) is a rare, life-threatening disease, and the diagnosis is often challenging. We herein report a 70-year-old man who suffered sudden cardiac arrest due to SCAR with pericardial fluid. ⋯ A careful retrospective CAG review showed slight contrast spillage from the distal LCx. SCAR should be suspected in patients with unknown etiology of pericardial effusion, and careful inspection of CAG is necessary.

An 82-year-old man with fever and back pain was referred to our hospital and was thus found to be thrombocytopenic. A bone marrow biopsy revealed the diffuse infiltration of poorly differentiated neuroendocrine carcinoma (NEC). Computed tomography revealed a large hepatic mass. ⋯ The patient rapidly deteriorated and died 10 days after presentation. An autopsy confirmed the diagnosis of primary hepatic NEC, with diffuse metastasis to the spleen, bone marrow, and systemic lymph nodes. This is an extremely rare case of NEC presenting with thrombocytopenia due to extensive bone marrow and splenic infiltration.

Bowel Obstruction due to Shiitake Mushrooms: Diagnostic Features on Computed Tomography.
Shiitake mushrooms are edible mushrooms popular in East Asian cuisine. We herein report a 69-year-old man with abdominal distension and vomiting after ingesting several pieces of sautéed Shiitake mushrooms. ⋯ After conservative treatment, he passed four pieces of Shiitake mushrooms. Despite the rarity, the condition can be diagnosed before exploratory surgery by careful and detailed interpretation of CT findings.
