A case of gaseous gangrene by Clostridium septicum associated with colorectal cancer is presented. The patient evolved rapidly towards septic shock and death. Autopsy showed occult neoplasm and pelvic and retroperitoneal myonecrosis. An exceptional finding was that of myocarditis in which thick gram-positive bacilli were identified. A review of the literature was carried out regarding the pathogenesis and clinical manifestations of this disease. The association of colonic neoplasm and Clostridium septicum may be related with the sensitivity of the cells of this neoplasm to the toxins of the microorganisms. The usefulness of this cytotoxicity is being tested in the therapeutic reduction of tumoral mass. With respect to clinical attitude, all the authors agree on the need for clinical suspicion as to the possible existence of occult colon neoplasm in individuals with septic shock by gaseous gangrene with no obvious entry site. Diagnosis is performed by imaging techniques with barium enema and if this is normal colonoscopy is carried out. Emergency treatment consists in laparotomy with resection of the neoplasm and debridement of the area accompanied by hyperbaric oxygen and antibiotics.

The case of a young female diagnosed with an IgG deficit and hepatic granulomas is presented. After 6 years of follow up the patient remains asymptomatic without treatment and with moderate biochemical cholestasis. The tests performed did not lead to a definitive etiologic diagnosis, therefore, according to a review of the literature, we believe that the granulomatous reactions are related with the hypogammaglobulinemia itself.

Galactorrhea as the result of hyperprolactinemia has been described in very rare cases associated to acute outbreaks of intermittent acute porphyria (IAP). In our country, any of such cases have been published or analytically documented. We present the case of a patient admitted in our hospital for the study of abdominal pain and galactorrhea, with latter diagnosis of IAP, supported by the assessment of the activity of the enzyme showing a deficit in the red blood cells.
