Atypical mycobacterial disease in children: a personal series.
Atypical mycobacterial disease is common in children in Australia. Over 22 years, records were kept prospectively by the senior author. The diagnosis was confirmed in 118 patients, either by culture or by the combination of a positive skin test plus typical histology. There were 46 boys and 72 girls with a median age at diagnosis of 28 months. Most children (n = 56) presented with chronic lymphadenitis or abscess formation (n = 55). The duration of illness varied from 4 days to 18 months. The most common sites affected were the head and neck (n = 112), with the pre-auricular region and anterior end of the submandibular triangle being characteristic. Nine patients had multifocal disease. The aim of treatment is to excise as much of the infected tissue as possible: 47 children had node excision through a planned incision that was closed primarily, with only 4 needing a second operation; 42 had excision of a node through the base of the superficial part of a collar-stud abscess with 6 recurrences. However, of the 33 children who had only drainage/curettage of the cavity or node 10 had recurrences requiring re-operation. Only 1 patient required a third operation. Morbidity was extremely low, with 1 staphylococcal wound infection. No child suffered permanent paresis of the mandibular division of the facial nerve. It is our belief that surgical excision of both the macroscopically affected and adjacent macroscopically unaffected nodes is necessary to achieve cure in the majority of cases.
