[Hyaline-vascular Multicentric Castleman's Disease in an immunocompetent patient]. / Enfermedad de Castleman Multicéntrica tipo hialino-vascular en paciente inmunocompetente.

A previously healthy, immunocompetent 67-year-old female presented with a one-month history of general symptoms, weight loss, night fevers, and bilateral lower extremity edema. On admission she had severe anemia, acute kidney injury, and multiple lymphadenopathies. An excisional biopsy of one of the axillary lymphadenopathies confirmed hyaline-vascular Castleman's disease. This rare disease is a polyclonal lymphoproliferative disorder that affects the normal lymph node architecture. According to its location it can be divided in unicentric (localized) or multicentric disease; it can be further divided according to histopathology in hyaline-vascular or plasmatic cells variety. Clinical presentation relates more to histopathological variety than to centricity. Human herpes virus 8 is ubiquitous in this disease and, along with interleukin 6, plays an important role in pathogenesis and symptoms presentation. Surgery is the go-to treatment of localized disease, while systemic chemotherapy is the option in multicentric disease. Communication between the clinical and anatomopathological teams is crucial; lag in diagnosis can lead to futile investigations in search of other diseases and delay in treatment.

Working situation and burden of work limitations in sarcoma patients: results from the multi-center prospective PROSa study.

PURPOSE: We investigated predictors of limitations in work performance, odds of drop out of work, and odds of receiving disability pension in sarcoma patients. METHODS: We measured clinical and sociodemographic data in adult sarcoma patients and recorded if the patients received a (1) disability pension at baseline or (2) had dropped out of work 1 year after initial assessment. (3) Work limitations were assessed using the Work-limitations questionnaire (WLQ©). We analyzed exploratively. RESULTS: (1) Amongst 364 analyzed patients, odds to receive a disability pension were higher in patients with abdominal tumors, older patients, high grade patients and with increasing time since diagnosis. (2) Of 356 patients employed at baseline, 21% (n = 76) had dropped out of work after 1 year. The odds of dropping out of work were higher in bone sarcoma patients and in patients who received additive radiotherapy ± systemic therapy compared with patients who received surgery alone. Odds of dropping out of work were less amongst self-employed patients and dropped with increasing time since diagnosis. (3) Work limitations were higher in woman and increased with age. Patients with bone and fibrous sarcomas were more affected than liposarcoma patients. Patients with abdominal tumors reported highest restrictions. Sarcoma treatment in the last 6 months increased work limitations. CONCLUSION: Work limitations, drop out of work and dependence on a disability pension occurs frequently in patients with sarcoma adding to the burden of this condition. We were able to identify vulnerable groups in both the socioeconomic and disease categories.
