An oral nightmare: A rare & refractory Crohn’s Disease case. When nothing seems to work !!! Dr. Weiner dror Wolfson Medical Center Department of Pediatric Gastroenterology and Nutrition Case: • R.D - An 18 year old men with Crohn’s disease (CD) diagnosed at the age of 9 years (Paris L3+L4a+p1) • Under went an Hartmann's procedure at 2012, with a colostomy that was closed 6 month following the operation. • Followed by another surgery were part of the large bowel was removed and an ileostomy was done. • Since 2014, evidence of inflamed rectal stump. • Severe perianal disease with multiple abscesses; trans and inter - sphincteric fistulae - setons placement. • Steroid dependent; MTX intolerance, Infliximab LOR (immunogenic). • Started on Adalimumab (40 mg every 2 weeks with a good trough level of around 11 mcg/ml). Case continuous: • In May of 2017 - multiple oral lesions (deep ulcers), lip swelling and angular cheilitis, exudate can be seen on the pharynx posterior wall. • Oral and Maxillofacial surgeons: diagnosed the lesions as oral crohn’s disease. • At biopsy: dense subepithelial lymphoplasmacytic infiltrate with no granulomas.

Clinical differentiation: Histopathologic differences: OCD OFG Differential diagnosis of granulomatous and non- granulomatous oral ulceration: Treatment: • For many patients with OCD, the oral findings are asymptomatic. • The majority of lesions resolves spontaneously over time.

Dapsone (50 mg a day than 100 mg and than 200 mg a day for a total of 4 weeks So we did an upper endoscopy: So, what is it ? Esophageal Crohn’s Infection ? But which one: Drug related eruption ? disease ? (Rare 0.2%) Bacterial ? Viral ? Fungal ? (SJS, TEN,DRESS) Other ? CMV Esophagitis: • The biopsy showed inclusion bodies (CMV infection) • And A positive PCR • He was treated with Ganciclovir for 10 day IV followed by Oral treatment to complete 21 days Second endoscopy after treatment 洛 And the oral nightmare continues: • About a mouth later – He had Worsening of Buccal Ulcers with swelling of left cheek, suspected parotitis? other? • Soft tissue US: no enlarged or hyper-vascular parotid glands, with normal appearing lymph- nodes. • He repeated the oral biopsy: inflamed squamous mucosa with ulceration and granulation tissue; immuno-staining for CMV was negative, And no granulomas were seen ! To conclude: 1) Sever crohn’s disease involving the proximal 1/3 of the small bowel 2) Sever oral involvement. 3) Sever esophageal disease. 4) Sever peri-anal involvement. 5) Anti – TNF – loss of response, on Stelara every 4 weeks !!!
