Its management is not well codified in the literature, and it can sometimes resist to usual therapies. Several molecules have proven to be effective in this situation. We report here the case of an intense paraneoplastic itch, resistant to antihistamines, and having responded to paroxetine, with a review of the literature. 2.?CASE REPORT We report the case of a 70\12 months\old woman followed for left breast malignancy with bone and pulmonary metastases. The patient was on palliative chemotherapy with EC (Epirubicin, Cyclophosphamide). After 9?days of the 3rd course of chemotherapy, the patient noted the appearance of a generalized itch which became more and more severe and caused her insomnia and a huge gene, without other associated indicators. Physical examination revealed diffuse scratching lesions throughout the body, associated with seborrheic scaling of the back evoking the Leser\Trelat sign (Physique?1). Biological examinations were normal, and viral serologies were negative. The diagnosis of paraneoplastic itch (PI) was the most plausible, in the absence of other etiologies. Then, the patient was initially put on an antihistamine with prescription of emollient and moisturizing creams. However, no improvement in symptoms was noted, and the pruritus persisted stubbornly. In the absence of a response, treatment with selective serotonin reuptake inhibitor (SSRI) was used: paroxetine (started at a dose of 10?mg/day at night then increased to 20?mg/day). Thus, after 4?days, there was a marked regression of the pruritus. Currently, the patient is undergoing capecitabine\centered chemotherapy (provided the quality 4 hematotoxicity offered the EC75 process), in the 8th treatment, with radiological and clinical balance of the condition. After a 6\month adhere to\up, the pruritus offers nearly vanished, NKP608 and the individual no requires paroxetine.

At the moment, there is absolutely no very clear description of PI, with regards to applicability nor with regards to duration neither. The SIG (unique curiosity group) on Paraneoplastic itch defines it the following: PI identifies the feeling of itch like a systemic (not really local) a reaction to the current presence of a tumor or a hematological malignancy neither induced by the neighborhood presence of tumor cells nor by tumor therapy. It generally disappears with remission from the tumor and may return using its relapse. 1 The real frequency NKP608 of the sign reminds unclear; epidemiological data with this field are limited. 2 From earlier studies, it really is known that we now have variations in the prevalence of itch with regards to the type of tumor. In hematological malignancies, the prevalence of itch can be greater than in nonhematologic malignancies. 3 Its prevalence is just about 30% in non\Hodgkin lymphomas, 3 , 4 and around 15%\50% in Hodgkin lymphomas. 4 Paraneoplastic itch might precede the analysis of the tumor. It could disappear when the tumor is treated and its own reappearance may announce tumor recurrence completely. 5 Also, the strength of pruritus could be correlated with the advanced stage of the condition.
