Abdominal Sinuses in a 23 yo Man

Three month history of draining sinuses lower abdomen.

HPI: This college student developed abdominal pain and bloody diarrhea in August of 2008. A diagnosis of ulcerative colitis was made and a number of theapies were tried (including prednisone and Remicaid). All were ineffective and he had a subtotal colectomy and ileostomy performed in December of 2008. Subsequent to that he continues to have some pain in the rectal stump and is scheduled for a J-pouch procedure in a few weeks. Three months ago, he developed painful draining tracts in the lower abdomen.

O/E: The patient is a healthy-appearing 23 yo man. The cutaneous findings are 5 - 10 mm in diameter sinus tracts with sero-sanguinous drainage. There are four active lesions at this time. The remainder of the cutaneous exam is negative.

Diagnosis: Could this be an extra-intestinal manifestation of inflammatory bowel disease? This is more common with Crohn's disease than U.C. My working diagnosis is sinus tracts or abdomino-cutaneous fistulae. The patient was referred for the question of pyoderma gangrenosum. If this is P.g., it is a very atypical case.

Questions:
Has anyone seen and treated a similar patient?
He is scheduled to have a resection of the rectal stump with a re-anastamosis of small bowel to the rectum allowing closure of his ileostomy (I am not sure of exact procedure). Perhaps this will help. Your thoughts are appreciated.

Pyoderma Gangrenosum

Abstract: 46 yo man with 1.5 year history of leg ulcers
History: The patient, a disabled 46 yo Cambodian man, has a four year history of poorly controlled ulcerative colitis. He has had painful leg ulcers for the past two years. These begin with pustules or vesicles by history. At present he is taking 1200 mg of Asacol t.i.d. and prednisone 30 mg. per day. In addition to the prednisone he has used potent topical steroids for his ulcers and has been treated at a wound care clinic.
Social History: The patient emigrated from Cambodia 25 years ago. He is married with three children and was employed until he became disabled 2 years ago from colitis and leg ulcers. His English is limited and I had no Cambodian translator.
O/E: There are two ulcers with raised overhanging borders on the left medial malleolus. In addition, there is post-inflammatory hyperpigmentation and proximal scarring secondary to previous ulcerations. The patient has Cushingoid facies.

Lab: N/A
Histopath: N/A
Diagnosis: Pyoderma gangrenosum (P.g.)
Discussion: There is no effective therapeutic protocol for P.g. He has been treated with high dose prednisone for months and his P.g. is only poorly controlled. Super-potent topical steroids have been used without improvement. It seems to us that tacrolimus ointment should be tried because there are many reports of its efficacy with P.g. and it is a more benign therapy than oral cysclsporin or mycophenolate mofetil. Colectomy may be a more permanent solution, but the patient and his gastroenterologists are not ready for that.
Questions: Your suggestions are welcome.

Because the incidence of pyoderma gangrenosum (PG) is low, no prospective randomized controlled trials and only a few studies with case numbers of more than 15 patients have been published. To date no guidelines for treatment of PG have been established far. The aim of the study was to provide an evidence-based review of the literature and an evaluation of recommendations for PG treatment. We performed an electronic search using the PubMed database and the term "pyoderma- gangrenosum." Literature published in the English language during the past two decades was reviewed. All relevant studies that could be obtained regardless of the study design were evaluated for grades of recommendation and levels of evidence. Data on patient characteristics including severity of the disease, localization of lesions, associated diseases, and treatment procedures were abstracted and evaluated for therapeutic outcome. We conclude that therapeutic efficacy of systemic treatment with corticosteroids and cyclosporine is best documented in the literature for disseminated as well as for localized disease and should be considered first-line therapy. In cases that do not respond to this treatment, we recommend alternative therapeutic procedures (eg, systemic treatment with corticosteroids and mycophenolate mofetil; mycophenolate mofetil and cyclosporine; tacrolimus; infliximab; or plasmapheresis), considering additional factors including associated diseases.
