253 usually appears after contact with infected animals or ingestion of contaminated milk; dissemination from a pulmonary focus is less common. Mycobacterium bovis is a member of the M tuberculosis complex, which includes the species M tuberculosis, M bovis, Mycobacterium africanum, Mycobacterium microti, and Mycobacterium canetti, 8 the causative agents of tuberculosis in humans and animals. Our review of the literature identified 4 cases of lupus vulgaris caused by M bovis in the past 20 years (Table 1). In 2005, Meyer et al. 3 described the case of a 69 year-old woman who had contracted pulmonary tuberculosis as a child. In 2009, Ta r et al. 7 and Flohr et al. 9 presented cases of patients suspected of having been infected with M bovis through contact with cattle or by ingesting unpas-teurized milk. In 2010, Twomey et al. 10 described a case of occupational infection with M bovis in a veterinarian. As a result of efforts to eradicate bovine tuberculosis and due to the prevalence of milk pasteurization, 9 lupus vulgaris caused by M bovis is now very rare. Nevertheless, it should be considered, primarily in patients who live in rural areas or work in high-risk occupations such as livestock rearing or veterinary medicine. 10 In conclusion, we present a case of lupus vulgaris caused by M bovis, now regarded as a very rare pathogen. This case involved a considerable delay in diagnosis, as the lesion had been present since childhood. Differentiation among members of the Mycobacterium tuberculosis complex by molecular and biochemical features: evidence for two pyrazinamide-susceptible subtypes of M bovis. tuberculosis due to Mycobacterium bovis lasting for more than 60 years.

Follicular lymphoma (FL) constitutes approximately 30% of all non-Hodgkin lymphomas in Western countries. Clinical presentation is typically in the form of lym-phadenopathy, hepatomegaly, splenomegaly and bone marrow infiltration. 1,2 Extranodal involvement is less frequent than in large B-cell lymphoma 2 and does not appear to affect prognosis; this is not the case with B-cell lymphoma. We report the case of a patient diagnosed with FL who developed skin nodules in the course of her disease. The ଝ Please cite this article as: Palacios Abufón A, et al.
