RESUMEN
OBJECTIVE: To determine the evolution, associated factors and the outcomes of transplanted people one year after the evolution of a cohort in Mexico. METHOD: Kidney transplant cohort from 2013 to 2017 in Mexico. 1118 patients were analyzed. Five outcomes were studied: overall survival, kidney graft, patient survival, delayed function, and acute dysfunction. Kaplan-Meier was used for kidney graft survival. For risk, bivariate and multivariate analyzes were performed with a significant value of p < 0.05. RESULTS: Of the 1118 kidney transplant patients, 57 (5.09%) had kidney graft loss, 52 (4.65%) died during the one-year follow-up; survival of the patient of 95.35% and of the graft 90.25%. CONCLUSIONS: The risk factors for the outcomes were transplantation from a deceased donor, recipient over 50 years of age and use of polyclonal agents. Infections and age are related to the death of the patient.
OBJETIVO: Determinar la funcionalidad del injerto renal a 1 año en una cohorte retrospectiva en México. MÉTODO: Cohorte de trasplante renal de 2013 a 2017 en México. Se analizaron 1118 pacientes. Se estudiaron cinco desenlaces: supervivencia global, supervivencia del injerto renal, supervivencia del paciente, función retardada y disfunción aguda. Para la supervivencia del injerto renal se usó Kaplan-Meier. Para el riesgo se realizó análisis bivariado y multivariado con valor significativo p < 0.05. RESULTADOS: De los 1118 pacientes con trasplante renal, 57 (5.09%) tuvieron pérdida del injerto, 52 (4.65 %) fallecieron durante el año de seguimiento; la supervivencia del paciente fue del 95.35% y la supervivencia del injerto fue del 90.25%. CONCLUSIONES: Los factores de riesgo para los desenlaces fueron trasplante de donante fallecido, receptor mayor de 50 años y uso de agentes policlonales. Las infecciones y la edad están relacionadas con la muerte del paciente.

BACKGROUND: Cysts are very common in the routine of dermatopathology but follicular germinative (trichoblastic) differentiation in cysts is seen rarely. The presence of follicular germinative differentiation in a cyst alerts to consider the possibility of a basal cell carcinoma (BCC) arising in a cyst. METHODS: Five cystic lesions with zones of follicular germinative differentiation were collected. Hematoxylin and eosin sections were reassessed for architecture, types of follicular differentiation and stromal characteristics; immunohistochemical studies with Ber-EP4 were analyzed. Articles about follicular germinative differentiation in cystic lesions were reviewed. RESULTS: Cystic lesions with follicular germinative differentiation have been described in the literature under various names including trichoblastic infundibular cyst, cystic trichoblastoma, cystic panfolliculoma (CPF), dermoid cyst with basaloid proliferations, folliculosebaceous cystic hamartoma and BCC occurring in infundibular cysts. The lesions presented by us could be classified as three cystic trichoblastomas, one CPF and one cystic hamartoma with follicular germinative differentiation. CONCLUSIONS: Histopathologically, cystic trichoblastomas can be separated from CPFs. Some lesions defy classification and may be regarded as cystic follicular hamartomas. The presence of follicular papillae and bulb-like structures, advanced follicular differentiation like that of inner and outer root sheath exclude the differential diagnosis of BCC arising in a cyst.
