Cutaneous paraneoplastic syndromes

Generalized herpes zoster and cutaneous metastasis during chemotherapy for non‐small cell lung cancer: A case report

“…The estimated mean survival after a diagnosis of cutaneous metastases has been reported to be 50% at six months, 6 and the median survival of 16 Japanese cases of skin metastasis from lung cancer approximately four months, 8 which is compatible with the present case. Cutaneous metastasis is typically located on the thorax, abdomen, head/neck, and scalp 6,15 . Some studies have reported that adenocarcinoma was the highest among cutaneous metastases from different histological types of lung cancer 7,15 .…”

“…The most common malignancies that metastasize to the skin are lung cancer in men, and breast cancer in women 6 . The estimated mean survival after a diagnosis of cutaneous metastases has been reported to be 50% at six months, 6 and the median survival of 16 Japanese cases of skin metastasis from lung cancer approximately four months, 8 which is compatible with the present case. Cutaneous metastasis is typically located on the thorax, abdomen, head/neck, and scalp 6,15 .…”

Unusual Paraneoplastic Presentation of Cholangiocarcinoma

“…Presence of photosensitivity, typical serology, supportive histopathology, association with history of cholangiocarcinoma, and raised tumor marker levels led to the diagnosis of paraneoplastic subacute cutaneous lupus erythematosus (p-SCLE). It is also in accordance with the criteria mentioned by McLean; that is, dermatoses arise after the development of malignant tumour and, secondly, both the dermatoses and the tumour follow a parallel course [ 3 ].…”

Putative paraneoplastic alopecia in a cat with apocrine adenocarcinoma

“…[2][3][4][5][6] The criteria for determining whether a dermatosis is paraneoplastic include (i) the dermatosis must occur after the development of a malignant neoplasia and (ii) both the dermatosis and the neoplasia must follow parallel courses. 10 In our case, the evolution of clinical signs, with the cutaneous mass on the head being the first observed, suggested that the apocrine adenocarcinoma preceded the development of alopecia and a possible cause/effect relationship. Unfortunately, surgical intervention was not feasible as a consequence of the inoperable nature of the tumour and the rapid deterioration of the patient's clinical condition, leading to her death.…”
