Infantile hypertrophic pyloric stenosis (IHPS) is one of the common surgical abdomen in infancy, characterized by progressive non-bilious vomiting. The etiology is unknown, but it likely develops after birth. The pylorus of the stomach becomes thick and triggers progressive vomiting. Abdominal ultrasonography (US) is widely used as a diagnostic tool. Currently, there is a rare IHPS patient with severe metabolic derangement because of general use of abdominal US and its accuracy. We experienced a natural course of a 62- day-old male infant with IHPS who was suffering from intermittent vomiting, loss of weight but had not been properly treated for 1 month. It is needed to make an effort to diagnose differentially in recurrent vomiting infant and check-up regularly, and also educate parents properly.

Disseminated Mycobacterium avium complex (MAC) infection can occur in immunocompromised patients, and rarely in immunocompetent subjects. Due to the extensive distribution of the disease, clinical presentation of disseminated MAC may mimic malignancies, and thorough examinations are required in order to make accurate diagnosis. We report a case of disseminated Mycobacterium intracellulare disease in an immunocompetent patient, which involved the lung, lymph nodes, spleen, and multiple bones. F-18 fluorodeoxyglucose positron-emission tomography imaging showed multiple hypermetabolic lesions, which are suggestive of typical hematogenous metastasis. However, there was no evidence of malignancy in serial biopsies, and M. intracellulare was repeatedly cultured from respiratory specimens and bones. Herein, we should know that disseminated infection can occur in the immunocompetent subjects, and it can mimic malignancies.
