    Seborrheic keratoses and severe hypoinsulinemic hypoglycemia associated with insulin grow factor 2 secretion by a malignant solitary fibrous tumor.
    Diabetol Metab Syndr 2016 29;8:33. Epub 2016 Apr 29.
    Endocrinology Division, Escola Paulista de Medicina, Federal University of São Paulo, São Paulo, SP Brazil.
    A rare sign of some malignant tumors is a sudden eruption of multiple seborrheic keratoses called Leser-Trélat sign. Overproduction of insulin-like growth factor-2 (IGF2) or its precursor is the main mechanism related to non-islet cell tumor hypoglycemia. Doege-Potter syndrome is the name given to paraneoplastic hypoinsulinemic hypoglycemia in presence of a solitary fibrous tumor. Read More

    Distant skin metastases as primary presentation of gastric cancer.
    J Community Support Oncol 2015 Apr;13(4):156-8
    Hematology-Oncology Section, Department of Medicine, The University of Oklahoma Health Sciences Center, Oklahoma City, Oklahoma, USA.
    Distant gastric metastasis to the skin is uncommonly a presenting symptom, although nonspecific paraneoplastic syndromes with dermatologic manifestation including diffuse seborrheic keratoses (Leser-Trelat sign), tripe palms, and acanthosis nigricans have been described in the literature. We report here the case of a 49-year-old woman with gastric adenocarcinoma who presented with cutaneous metastasis as an initial symptom. In our case, metastatic skin lesions responded significantly to EOX chemotherapy (epirubicin+oxaliplatin+capecitabine) despite progression of systemic disease. Read More

    Leser-Trélat sign presenting in a patient with recurrent pre-B-cell acute lymphocytic leukemia.
    Cutis 2012 Jan;89(1):33-5
    Naval Hospital, Jacksonville, Florida, USA.
    The presence of multiple seborrheic keratoses appearing abruptly in association with an underlying malignancy is known as Leser-Trélat sign, a rare paraneoplastic cutaneous syndrome. Although this finding is most commonly associated with solid organ tumors, it also can be a clue for the presence of underlying hematologic malignancies. We present a unique case of Leser-Trélat sign in a 20-year-old man who experienced a relapse of pre-B-cell acute lymphocytic leukemia (ALL) that was previously treated with multiple courses of chemotherapy and external radiation therapy.
