Se presenta el caso clínico de una paciente de 52 años con diagnóstico de tuberculosis de cadera derecha a quien en 1991 se le instala prótesis de Titanio. Once años después presenta aumento de volumen de la extremidad inferior y masa palpable en zona inguinal. Fue estudiada con ultrasonografía y tomografía computada cuyos hallazgos se describen. Se planteó como diagnóstico diferencial principal un sarcoma en compartimiento iliopsoas por lo cual se realiza biopsia bajo ultrasonografía que demostró metalosis por Titanio diagnóstico que debe ser considerado en pacientes con masa inguinal y prótesis de cadera.

Eleven years later, she presented low extremity swelling and inguinal mass, which was studied with ultrasound and computed tomography. The main differential diagnosis was an iliopsoas sarcoma, so an ultrasound-guided biopsy was performed. The result was Titanium particle debris. The lesion was removed, but it recurred, so that joint replacement was required. Joint Titanium particle wear debris a condition due to particle releaseis as an arthroplasty complication. When its clinical manifestation is a pelvic mass, the main differential diagnoses include tumors and granulomatous disease. Both clinical manifestations and the radiology are variable. This pathology in patient with hip joint Titanium arthroplasty must be consided

To determine the viability of micrografting of Valencia orange and Tahiti Lime plants on Cleopatra mandarin rootstocks for possible use in massive plant propagation, different steps o the micrografting procedure were evaluated. Seeds of Cleopatra mandarin were established in semisolid MS (Murashige and Skoog) with, or without, GA3 to evaluate the effect on percentage and time time of germination. Plants of Valencia and Tahiti were, either, treated with 1 mg l -1 BAP or manually pruned to evaluate the effect on vegetative shoot production, and the effect of three positions of the shoot tip meristem (Topping, sided and slant) onto the decapitated surface of the rootstock on the percentage of success were evaluated. Treatments for all experiments were distributed with a complete randomized design and data for vegetative shoot production were analyzed with ANOVA and means separated with Tukey test. Results evidenced that GA3 had no effect on increasing percentage and reducing time of germination, pruning statistically increased the number of vegetative shoots in plants. Micrografting success of 28% for Valencia orange and 14% for Tahiti lime are consistent with reported studies for recovery of disease-free plants; however, to increase success level for massive plant propagation, it is recommended for further studies to consider evaluation of in vitro conditions such as increased sucrose concentration, in vitro adaptation of shoot tip meristems and auxin supply, among others.
