1/41. acanthosis nigricans and wart-like lesions associated with metastatic carcinoma of the stomach.A 63-year-old white man developed malignant acanthosis nigricans one year after a hemigastrectomy for adenocarcinoma of the stomach. Multiple "wart-like" lesions involving the dorsa of the hands, arms and trunk were also present. The malignant acanthosis nigricans in the patient appears to have paralledled the course of the metastatic gastric adenocarcinoma. Discrete verrucous lesions can occur in malignant acanthosis nigricans which histopathologically may show either squamous or basal cell hyperplasia.- - - - - - - - - - ranking = 1keywords = adenocarcinoma, carcinoma (Clic here for more details about this article) |
2/41. oral manifestations as a hallmark of malignant acanthosis nigricans.We present a case of malignant acanthosis nigricans (AN) that initially manifested in the oral cavity. In the present report, the patient had typical clinical and histological findings of oral and esophageal AN, with subtle skin changes, associated with a gallbladder adenocarcinoma. The importance of the clinical oral examination is emphasized because the recognition of oral lesions led to the diagnosis of AN and to the following detection of the internal malignancy. Since the tumours associated with AN are highly malignant, it is of the utmost importance to recognize the skin and mucous membrane changes in adults.- - - - - - - - - - ranking = 0.40348165378057keywords = adenocarcinoma, carcinoma (Clic here for more details about this article) |
3/41. Malignant acanthosis nigricans: potential role of chemotherapy.acanthosis nigricans is an uncommon skin condition characterized by hyperkeratosis and skin hyperpigmentation. Most causes are benign, but it may also be associated with gastrointestinal and other malignancies. When associated with malignant disease, the skin pathology may be more severe and treatment often unsuccessful. We describe a 66-year-old man with acanthosis nigricans associated with carcinoma of the stomach, with distressing generalized cutaneous, perioral and perineal disease, whose skin condition resolved completely with combination chemotherapy. In patients with malignant acanthosis, chemotherapy may relieve many of the distressing cutaneous symptoms. A close liaison between gastroenterologists, dermatologists and oncologists is required.- - - - - - - - - - ranking = 0.048259173109715keywords = carcinoma (Clic here for more details about this article) |
4/41. Coexistence of acanthosis nigricans and the sign of Leser-Trelat in a patient with gastric adenocarcinoma: a case report and literature review.The association of acanthosis nigricans (AN) with the sign of Leser-Trelat (LT) and gastric carcinoma is rare. Our patient was a 69-year-old man, who presented with hematemesis; a stage-IV poorly differentiated, diffuse-type, adenocarcinoma of the gastric antrum was diagnosed. The AN was striking, with florid cutaneous papillomatosis that also involved the mucous membranes of the mouth and eyelids, and keratoderma. AN and the sign of LT predated tumor detection by 6 months and regressed after chemotherapy in parallel with reduction of the tumor load, demonstrating the dermatoses as paraneoplastic phenomena. The patient died 7 months after completion of chemotherapy. The coexistence of AN and the sign of LT should prompt a search for underlying malignancy. The pathogenesis of both dermatoses is discussed.- - - - - - - - - - ranking = 2.0656674420126keywords = adenocarcinoma, carcinoma (Clic here for more details about this article) |
5/41. The sign of Leser-Trelat in a case of adenocarcinoma of the lung.This is what we believe to be the first report of the sign of Leser-Trelat in association with occult adenocarcinoma of the lung. The sign of Leser-Trelat is proposed as a sign of possible occult malignancy, despite various suggestions to the contrary. Also, it is suggested that a tumor-produced humoral factor (eg, transforming growth factor-alpha [TGF-alpha]) could be responsible for both the acute eruption of the monomorphous seborrheic keratoses and the nearly concomitant development of acanthosis nigricans, which occurred in our case. The possible distinction between a hyperplastic and a neoplastic origin of various types of seborrheic keratosis is discussed in relation to this hypothetical humoral factor. In addition, we suggest a refinement of the definition of the sign of Leser-Trelat and discuss the use of "sign of Leser-Trelat" and "syndrome of Leser-Trelat" in relation to physical findings. All patients with the sign of Leser-Trelat should undergo a thorough evaluation for occult malignancy.- - - - - - - - - - ranking = 2.0174082689028keywords = adenocarcinoma, carcinoma (Clic here for more details about this article) |
6/41. Florid cutaneous and mucosal papillomatosis with acanthosis nigricans revealing a primary lung cancer.This is the report of an 80-year-old patient with diffuse brownish hyperpigmentation and velvety thickening of the skin with onset 1 year before. Warty lesions on his limbs were present as well as papillomatous and verrucous lesions on his lips, mouth and eyelid conjunctivae with hyperkeratosis of the nipples. Biopsies, performed at different sites, showed histological pictures consistent with a diagnosis of acanthosis nigricans (AN) with florid cutaneous and mucosal papillomatosis. This type of AN is frequently associated with internal malignancy. In our patient serum levels of tissue polypeptide antigen, carcinoembryonic antigen, cytokeratin fragment and squamous cell carcinoma antigen were high and chest computed tomography scan indicated a large tumour infiltrating the right lung and extending to the mediastinum. Cytological examination of bronchial drainage revealed the presence of neoplastic cells, non-small cell type carcinoma. The most frequent cancer associated with malignant AN is gastric adenocarcinoma. lung tumour has rarely been reported with AN. Malignant AN is sometimes associated with other cutaneous and mucosal warty lesions, as in our patient. These various skin and mucosal lesions are the expression of a systemic epithelial disorder and may help clinicians to suspect a malignant form of AN.- - - - - - - - - - ranking = 0.5keywords = adenocarcinoma, carcinoma (Clic here for more details about this article) |
7/41. Oral acanthosis nigricans as a marker of internal malignancy. A case report.BACKGROUND: acanthosis nigricans (AN) is a rare mucocutaneous condition that can involve the oral tissues. There are 2 clinical forms of AN: benign and malignant. Benign AN is related to systemic diseases such as diabetes and obesity or can be induced by drugs such as systemic corticosteroids, nicotinic acid, estrogens, insulin, and fusidic acid. Malignant AN appears in association with tumors such as lung, ovarian, breast, and gastric carcinoma. methods: A rare case of malignant AN that initially manifested in the oral cavity of a 73-year-old patient is reported. RESULTS: A bladder and lung carcinoma were detected following the diagnosis of AN. CONCLUSIONS: The diagnostic importance of oral AN is emphasized because, in our patient, its recognition led to the detection of 2 occult malignant tumors.- - - - - - - - - - ranking = 0.096518346219431keywords = carcinoma (Clic here for more details about this article) |
8/41. acanthosis nigricans with endometrial carcinoma: case report and review of the literature.BACKGROUND: acanthosis nigricans is classified into benign and malignant forms on the basis of clinical associations. The main interest in acanthosis nigricans has been based on its association with malignancy because of the dramatic clinical appearance of the skin lesions and the usually rapidly fatal nature of the underlying disease. "Tripe palms" is a descriptive term of acanthosis nigricans of the palms. It more often is associated with internal malignancy. Most importantly, it often precedes the diagnosis of a new or recurrent tumor. Malignant acanthosis nigricans is most commonly associated with intra-abdominal malignancies. There are very few reports in the literature of malignant acanthosis nigricans associated with gynecological malignancies. Only five cases of endometrial carcinoma associated with acanthosis nigricans and/or tripe palms have been reported in the literature. CASE: A 69-year-old African-American female presented with skin changes consistent with the diagnosis of acanthosis nigricans and tripe palms. More than 14 months later she was found to have endometrial carcinoma. She subsequently underwent total abdominal hysterectomy and salpingo-oophorectomy followed by chemotherapy with paclitaxel and carboplatin. During treatment of the underlying malignancy the skin condition dramatically improved. CONCLUSION: Tripe palms can be associated with endometrial carcinoma and may be the first sign of malignancy. Malignant acanthosis nigricans may improve with treatment of the underlying malignancy. patients who present with tripe palms may need to undergo workup to search for underlying malignancy.- - - - - - - - - - ranking = 0.33781421176801keywords = carcinoma (Clic here for more details about this article) |
9/41. Host-vs.-altered-host eruptions in patients on liposomal doxorubicin.BACKGROUND: Anthracycline antitumor antibiotics are the most commonly used chemotherapeutic agents. One of these is doxorubicin. Liposomal doxorubicin was developed as a drug delivery system in order to deliver the active drug intracellularly while decreasing the systemic toxicity, particularly hematological and cardiac toxicity. methods: The clinical and histologic findings of the cutaneous eruptions of associated with liposomal doxorubicin are reviewed. RESULTS: The eruptions occurred in three women with metastatic ovarian carcinoma who were treated with liposomal doxorubicin. These three patients developed erythematous macular/papular to plaque cutaneous lesions, and in one patient a vesicular component. The eruptions involved the trunk and extremities approximately 3-4 weeks after completions of therapy. None of the patients had any documented infections, and none of the patients had symptoms other than pruritus. The eruptions cleared over a period of weeks to months. Histologic features included an interface dermatitis with numerous apoptotic/dyskeratotic cells within the epidermis, with involvement the intra-epidermal sweat ducts and the infundibulum of hair follicles. CONCLUSION: We believe that these eruptions represented a chemotherapy induced host-vs.-altered host reaction.- - - - - - - - - - ranking = 0.048259173109715keywords = carcinoma (Clic here for more details about this article) |
10/41. Malignant acanthosis nigricans and endometrioid adenocarcinoma of the parametrium: the search for malignancy.Malignant acanthosis nigricans is recognized as a cutaneous sign of internal malignancy, usually an adenocarcinoma. Although cases of malignant acanthosis nigricans have been associated with cervical, ovarian, and endometrial neoplasms, we describe a case with a rarely if ever reported association, endometrioid adenocarcinoma of the parametrium.- - - - - - - - - - ranking = 2.4208899226834keywords = adenocarcinoma, carcinoma (Clic here for more details about this article) |
