ABSTRACT
A 35-year-old woman was treated with chemotherapy for leukemia. One year later, allogeneic hematopoietic stem cell transplantation (HSCT) was performed with umbilical cord blood. After nine months, she developed a spiking fever, sore throat, arthralgia, pleural effusion, hyperferritinemia, and persistent generalized pruritic erythema. A skin biopsy showed dyskeratotic cells in the epidermis, neutrophil infiltration in the epidermis and upper dermis, and neutrophils in the parakeratotic layer. Treatment with tocilizumab was effective. Adult-onset Still's disease (AOSD)-like disease related to graft versus-host disease (GVHD) after HSCT was suspected. Abnormal immune states related to GVHD may cause AOSD-like disease with more severe skin lesions than usual.

Systemic inflammatory response markers, including neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and monocyte-to-lymphocyte ratio, are useful prognostic factors for various malignant tumours. The aim of this study was to investigate the clinical relevance of these markers in primary cutaneous angiosarcoma. Twenty-six patients were retrospectively divided into 2 groups according to pretreatment peri-pheral blood cell counts or systemic inflammatory response marker levels; overall survival and progression-free survival were compared. Univariate analysis found that high neutrophil count (> 3.1×109/l), high neutrophil-to-lymphocyte ratio (> 2.4), high platelet-to-lymphocyte ratio (> 175) and low lymphocyte count (≤ 1.3×109/l) were related to shorter overall survival, while high neutrophil and low lymphocyte groups had shorter progression-free survival. In multivariate analysis, high neutrophil count and high neutrophil-to- lymphocyte ratio (hazard ratio 7.44 and 5.04, 95% confidence interval 1.48-37.2 and 1.26-20.1, respectiv-ely) were identified as independent prognostic factors for poor overall survival. These results indicate that systemic inflammatory response markers serve as prognostic predictors in primary cutaneous angiosarcoma, as well as in other types of soft-tissue sarcoma.

A case of xeroderma pigmentosum (XP) group D in a 39-year-old Japanese man is reported. The patient had suffered from moderate to severe solar sensitivity and freckle-like pigmented macules in sun-exposed areas since 6 years of age, and developed skin malignancies such as squamous cell carcinoma, actinic keratosis, Bowen's disease and basal cell carcinoma. The minimal erythema dose for ultraviolet (UV) radiation was decreased with a delayed peak reaction. The level of unscheduled DNA synthesis of fibroblasts from the patient was 70% of normal, while they expressed POLH, a gene product responsible for the XP variant. Whole-exome sequencing indicated that the patient harbored a homozygous mutation of c.1802G>T, p.Arg601Leu in ERCC2. A genetic complementation test was carried out by host cell reactivation assay, which showed that the patient's fibroblasts recovered only when they were transfected with XPD cDNA, confirming the diagnosis of XP-D. Arg601Leu mutation in ERCC2 may be related to mild UV radiation sensitivity and moderate skin lesions.
