[PAGID] Eosinophilic abscesses in a CGD patient

[Kate Sullivan]

I am not sure but I have seen lots of eosinophilic bladder processes that resolved rapidly with steroids.

The PPD would make me nervous but you could cover with anti-mycobacterial drugs until the cultures are mature and then treat with steroids.

He has had multiple episodes of cervical lymphadenitis, requiring parenteral antibiotics.   He is maintained on interferon gamma (3x/week) and Ciprofloxacin (TMP/SMZ caused leukopenia and thrombocytopenia).  Other medications are iron and multivitamin daily.

Milk elimination did not help.  In Jan 2010, EGD showed chronic duodenitis, and colonoscopy showed many areas with crypt distortion, prominent lamina propria eosinophils and rare intraepithelial eosinophils.  Granulomas were not seen.  He was started on Apriso (mesalamine) in early April to treat inflammatory bowel disease.

He then developed abdominal distension and a new hydrocele over a short period of time, due to bulky lymphadenopathy involving the mesentery and retroperitoneum.  A PPD was placed and was positive with 15 mm induration.

No acid fast organisms were seen in the lymph nodes.   Cultures are still negative but it has been only 2 weeks so far.  However, the lymph node histology was a complete surprise to us.  There were granulomas, but the center of many of them were filled with abscesses of eosinophils!
