case_images: Act-D chemotherapy (8-10 microg/kg x 8 d), which was also repeated every 2 weeks. After 2 courses of the Act-D chemotherapy, the beta-HCG returned to normal levels (Figure 2).
case_images: HFSR was caused during Act-D chemotherapy. Pictures show different grades.. Notes: (A) After the 2 courses of Act-D chemotherapy, mild edema, blister, and obvious erythema were observed in the palmar and metatarsal part of the foot, and the surface of the erythema was covered with exudate, and the peripheral skin was dried and desquamated. (B) After the 3 courses of Act-D chemotherapy, multiple ulcers were seen in the palmar and metatarsal area of both hands and feet, and the depth of ulcers varied from 1 to 3 mm. Bleeding and exudation were found on the surface of ulcer. The ulcer surface was covered with black scabs surrounded by a red halo, and the peripheral skin was dried and desquamated..

Only 3 days after finishing of the treatment, the patient suffered from fever and severe HFSR (manifestation of ulcerative dermatitis) (Figure 3B).
case_images: Histopathology in Act-D chemotherapy was associated with HFSR (H&E staining) (A: 4x; B: 10x; C: 40x): Epidermal defect, ulcer formation, a great number of neutrophils, fibrinoid degeneration of the inferior vascular wall, infiltration of perivascular lymphoid cells, neutrophils, some eosinophilic leukocytes, and proliferation of fibroblasts.. Abbreviation: HFSR, hand-foot skin reaction.
