Skin toxicity in a patient with ovarian cancer treated with pegylated liposomal doxorubicin: A case report and review of the literature

Pegylated liposomal doxorubicin (PLD) is a form of doxorubicin enclosed in pegylated liposomes. In contrast to conventional doxorubicin, PLD is characterized by a lower incidence of cardiotoxicity and myelosuppression. However, it induces specific mucocutaneous side effects, particularly palmar-plantar erythrodysesthesia (PPE). Other dermal manifestations, such as intertrigo-like dermatitis, diffuse follicular rash, melanotic macules, maculopapular rash or recall phenomenon are less common. Mechanisms that lead to skin toxicity remain unclear, however, certain reports indicate that drug excretion in sweat, host-vs.-altered-host reactions and local mechanical microtrauma play an important role in the development of cutaneous disorders. Effective preventive and curative management has not yet been established. The current study reports a case of a 55-year-old patient with advanced ovarian cancer who developed an uncommon diffuse maculopapular rash and severe PPE during treatment with PLD. Complete regression of the skin disorder was observed after 4 weeks. At present, palliative chemotherapy provides the opportunity to prolong life and alleviate disease symptoms, nonetheless it produces a number of adverse effects. Dermal complications may affect patient quality of life and cause therapy interruption. In the light of widespread use of PLD, skin toxicity associated with this drug creates a major problem.

Secondary cancer in a survivor of Hodgkin's lymphoma: A case report and review of the literature

Hodgkin’s lymphoma (HL) is one of the most curable malignant diseases in adults. However, HL patients have a higher risk of developing second malignancies compared with the general population. The population of adult cancer survivors is growing, thus, the long-term effects of cancer treatment, including secondary cancer development, have become an increasingly important concern in the field of oncology. The current study presents the case of a female HL survivor who developed two secondary malignancies within 29 years of follow-up. Furthermore, a review of the literature was conducted, which focused on secondary breast and gastrointestinal cancers in HL survivors.

Malignant acanthosis nigricans associated with prostate cancer: a case report

Background

Acanthosis nigricans is characterized by hyperpigmentation and hyperkeratosis of the skin or mucous membranes. Its malignant form is associated with internal neoplasms, especially gastric adenocarcinoma (55–61%). Coexistence with prostate cancer is uncommon. In the paraneoplastic type of this dermatosis, the skin and mucous lesions are characteristically of more sudden onset and more severe than those in the benign form. The efficacy of various treatment strategies remains disappointing.

Case presentation

We here report a case of 66-year-old Caucasian patient with metastatic prostate cancer and a mild form of acanthosis nigricans that preceded the diagnosis of malignancy and resolved with chemotherapy in parallel with the prostate cancer. The dermatosis recurred when the prostate cancer progressed.

Conclusion

Concurrent acanthosis nigricans and prostate cancer is rare, and few such cases have been reported. Anti-tumor therapy occasionally results in regression of this dermatosis. Underlying malignant disease should be suspected in individuals with elderly-onset of acanthosis nigricans.
