A 44-year-old female, without previously known diseases, underwent a total hysterectomy following the diagnosis of a symptomatic myoma, about 8.4 cm × 7.9 cm. She reported lower abdominal pain and fullness for 2 weeks, without other complaints. The final pathological report revealed a leiomyosarcoma, and the positron emission tomography scan performed subsequently, showed no evidence of metastatic dissemination. The patient started adjuvant single-agent chemotherapy with pegylated liposomal doxorubicin (PLD) at a dose of 50 mg/m2. By the fourth cycle, she referred itching, redness, and impaired skin sensitivity on both hands but particularly on both feet. On physical examination, erythema, edema, and desquamation on both feet, and in a milder pattern, both hands were found. Grade 2 hand–foot syndrome or palmar-plantar erythrodysesthesia (PPE) was diagnosed [Figure 1], and the patient was given topic medication – Neo-Cortisone Cream (hydrocortisone 1% and neomycin Sulfate 0.5%) and Doxepin Hydrochloride Cream 5%, 3–4 times/day – and advised to avoid extreme temperatures and excessive pressure or friction to the skin. According to the toxicity grades of PPE and dose modification guidelines,[1] PLD administration was delayed by 2 weeks, and progressive improvement of the symptoms was seen. Consequently, dose modification was not necessary, having completed the six intended cycles. PPE, also called hand–foot syndrome, is a relatively common dermatologic toxicity related to chemotherapy.[1] Although its pathogenesis is unclear, increased drug concentration in the eccrine glands of the palms and soles, the rapid cell division, vascular anatomy, temperature gradients, and gravitational forces, specific of these areas are mentioned factors.[1-3] The liposome-encapsulated form of doxorubicin is associated with a higher incidence of PPE than the nonencapsulated form, particularly when initial doses >40 mg/m2 are administered.[1,2] PPE of any severity grade is observed in up to 50% of individuals treated with PLD and optimal management remains undefined, making it an important reason for PLD dose modification or treatment withdrawal.[1-3] Therefore, it is important to be aware of this condition, its classification/grading and management, avoiding whenever possible, modifications in the chemotherapeutic regimen.
