Chronic granulomatous disease mimicking early-onset Crohn’s disease with cutaneous manifestations

چکیده
BACKGROUND Chronic granulomatous disease is a rare inherited disorder of the innate immune system. In patients with a clinical history of recurrent or persistent infections, especially infections caused by uncommon species, chronic granulomatous disease should be considered. CASE PRESENTATION We report the case of a 5-year-old boy with a presumptive diagnosis of Crohn's disease with extraintestinal manifestations. Chronic granulomatous disease was suspected in this case after Serratia marcescens was isolated from a skin ulcer culture. Granulomas were confirmed on histology and chronic granulomatous disease was diagnosed. CONCLUSION This case emphasizes the importance of high clinical suspicion of an alternative diagnosis of immune deficiency in patients with presumed inflammatory bowel disease and opportunistic infections, especially when disease occurs in early life.

CCD is divided into a genital type and an extra-genital type, each with their own unique different clinical manifestations. The usual presentation of genital Crohn’s disease (CD) is in the form of erythema and edema of the labia and scrotum. Here, we...

Hidradenitis suppurativa affects apocrine gland-bearing areas of skin and may produce perianal lesions clinically indistinguishable from the cutaneous manifestations of Crohn’s disease1, suggesting an association between the two diseases1–3. A recent histological study3 of hidradenitis suppurativa described epithelioid granulomas in 10 per cent of cases. Some of these patients had systemic gran...

B-cell chronic lymphocytic leukemia (B-CLL) is a low-grade lymphoproliferative disease. Cutaneous involvement of B-CLL is limited and, in most cases, it represents non-specific manifestations related to an impaired immune system. Leukemic skin infiltrates (leukemia cutis) occur in 4-20% of patients. Herein we report the case of a 65-year-old woman with B-CLL presenting with papular, nodular, an...

This case report describes a patient with cutaneous signs in the genital and peri-anal region suspicious of Crohn’s disease without any intestinal symptom or sign. Inflammatory bowel disease can be associated with some cutaneous signs. However, in this paper, we report a patient with isolated cutaneous Crohn’s disease which is very rare (less than 100 case reports across the world). Our patient...
