Taxanes and anthracyclines argon the antineoplastic drug groups most commonly implicated. Nail changes can take on several or each 20 nails and appear in worldly relationship with drug intake. Most of the quantify, toxicity is just a depicted object of concern due to cosmetic reasons, however very occasionally it whitethorn be associated with pain. True incidence of nail changes related to particular drugs are still lacking due to under-reporting and ignorance of potential side-effects among the endurings, necessitating the education prior to mental home of drugs and appropriate management like, avoiding potential irritants and use of topical, or oral antimicrobials, and peradventure cessation or dose reduction of the offending agent or use of cryotherapy in near cases may certainly be beneficial. substructureChemotherapeutic drugs are associated with variety of nail changes. These nail changes are normally temporarily and use to resolve once chemo toxic drugs are stopped. prevalent drugs ingraining are hydroxyurea, cyclophosphamide, vincristine, doxorubicin, dexamethas mavin, methotrexate and cytarabine. We here report our experience with devil patients who developed nail changes during the course of chemotherapy for hematological malignanciesCase Report 1A 19-year-old young boy was admitted to the our hospitals hematology prison cellblock with the symptoms of fever and lymphadenopathy in cervical and axillary region .Workup including bone internality examination, PET CT scan, excisional biopsy of lymph node were through and diagnosis of T cell rich B lymphoblastic lymphoma STAGE IIIB was made .He received 1st rhythm method of RCHOP while hospitalized and later on discharged .He received rest of seven RCHOP courses on outdoorsy basis. Through examination during his outdoor follow up visits revealed transverse hyper pigmented bands on the nails (chromonychia). The bands were multiple, transverse, some 1-mm broad, spanning the entire nail breadth, dark grayish colored, nonblanchable, nonpalpable with smooth superimposed nail surface on the nail plates of all fingers and toes with well appreciation of step in faintly grey colored bands of nails(Figure 1,2). Unluckily, he relapsed post eight cycles of RCHOP chemotherapy and henceforth started on 2nd line chemotherapy sieve (Rituximab, ifosfamide, cisplatin, etoposide), 1st course of which was precondition to him uneventfully recently till the time of writing this report.Case Report 2A 55-year- old young-bearing(prenominal) presented to hematology clinic with complaints of pain abdomen for 6 months with history of significant firing of weight and appetite. Per abdomen examination revealed presence of abdominal lump with dimensions of 18 cm x 15 cm with no hepatosplenomegaly.Tru-cut biopsy of lump was done .Histopathological examination and immunohistochemistry confirmed high grade, B cell type non-Hodgkins lymphoma. She was further investigated and found to hit stage IVB disease .Due to financial issues she was given CVP regimen (cyclophosphamide,doxorubicin,vincristine),however she relapsed following 3 courses by the time of writing this report. During her outdoor visits, she was found to have diffuse, black pigmentation with longitudinal striae in the nails of digits of both pass on (figure 3, 4) and feet.DiscussionAmongst the innumerable side effects that chemotherapeutic drugs have, mucocutaneous one are the most worrisome for the pa tients probably due to cosmetic reasons. assorted patterns of nail discoloration like chromonychia, leukonychia (including Mees and Muehrckes lines), Beaus lines, paronychia and onycholysis have been well documented(1). Drugs commonly implicated are vincristine, hydroxyurea, etoposide, daunorubicin, bleomycin, cyclophosphamide, dacarbazine, 5-fluorouracil and methotrexate (1, 2).The most frequent variety of chromonychia is melanonychia which is outgo defined as a dark pigmentation of nails observed as diffuse, transverse, or longitudinal band patterns(2).Some more common and fundamental nail toxities have been summarized in table 1 with their description of morphology and pathophysiology of origin.Effect of cyclophosphamide on nails ranges from diffuse, black pigmentation to dark longitudinal striae , and diffuse, dark gray pigmentation located proximally, with overlying transverse, black bands(2). Doxorubicin produces commonly transverse, dark brown bands alternating with white chevron and dark brown diffuse pigmentation bands 45 mm wide, which affect two-thirds of the distal portion of the nail(3). Hydroxyurea produces pigmentation that has a diffuse, dark brown color which may appear as single or double transverse bands. Our patient received all of the above mentioned drugs during his due course of illnessTable1. Definitions of some common nail toxities and probable pathophysiology of origin (1, 2)ConclusionNail changes although seems to be common following chemotherapy, however goes unnoticed and underlooked in the lights of more important burning issues of chemotherapy both by physician and patient and hence honest incidence of nail related changes is much more than reported oddly in dark colored individuals like our patient and hence requires smashing observation during follow up of these patients.References1.Hinds G, Thomas VD.
