Idiopathic recurrent pyoderma gangrenosum with cobalamin deficiency in a 62-year-old male: a case report.

UNLABELLED

Pyoderma gangrenosum (PG) is a rare, neither infectious nor gangrenous, neutrophil-mediated inflammatory dermatosis. In 50-70% of cases, systemic disease is the underlying cause, and the remaining is idiopathic.

CASE PRESENTATION

The authors here present a case of a 62-year-old male with a history of recurrent ulcer over the dorsum of hand diagnosed with recurrent PG with cobalamin deficiency treated with intralesional steroid injection and topical antibiotics along with intramuscular vitamin B12 injections. The patient returned after a year with a history of swelling in the left hand for 1 week, which was managed with intravenous antibiotics.

CLINICAL DISCUSSION

The most common kind of PG is ulcerative, which accounts for around 85% of cases that have been found. Ulcerative PG begins as small, painful erythematous or violaceous papules and pustules that quickly develop into ulcers with an exudative, mucopurulent, hemorrhagic base or with areas of necrosis and high, well-defined, serpiginous, violet-blue, or metallic grey borders, which are its defining feature. Glucocorticoids, along with a wide range of additional systemic immunomodulatory medication as alternatives and antibiotics to prevent infection are used for treatment.

CONCLUSION

PG is a rare form of neutrophilic dermatosis that can be difficult to diagnose and treat. PG has a mixed nutritional deficiency and a history of ulcers. It is crucial to have a high degree of suspicion when making a diagnosis, as well as to look for associated diseases and start treatment as soon as possible.
