[Successful treatment with biweekly CHOP for bone marrow relapse of blastic plasmacytoid dendritic cell neoplasm].

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematological malignancy derived from precursors of plasmacytoid dendritic cells. The majority of patients initially respond to multi-agent chemotherapy, though most relapse within a year and the prognosis is very poor. We report a 67-year-old man with erythema on the right chest and a nasopharyngeal mass.

[Primary gastrointestinal follicular lymphoma of the small intestine with massive hemorrhage: a report of three cases].

Primary gastrointestinal follicular lymphoma (FL) has an indolent clinical presentation and many of cases are diagnosed incidentally during routine endoscopic examinations. Herein, we present 3 cases with FL of the small intestine developed massive intestinal hemorrhage that necessitated blood transfusion. In all three patients, upper and lower endoscopic examinations failed to detect the bleeding sites.

Outcomes of planned delivery delay in pregnant patients with invasive gynecologic cancer.

Background: Pregnancy with invasive gynecologic cancer is a rare condition. It is still unclear whether we can choose planned delay in treatment until maturation of the fetus as a treatment modality for this condition. If there are no adverse effects from the cancer and there is improvement of neonatal outcomes, this treatment modality might be an option for patients with this condition.

Gaps and fragmentation of the superficial cortex in the abdominal and pelvic lymph nodes of elderly Japanese.

Gaps and fragmentation of the superficial lymph node cortex are considered to provide intranodal shunt flow between the afferent and efferent vessels. Using serial sections of 205 nodes obtained from 27 donated cadavers more than 70 years of age, we examined the histological architecture of the abdominal and pelvic nodes in elderly Japanese. Secondary follicles were rare in the specimens.
