A patient presenting with a unilateral leg stasis dermatitis was initially misdiagnosed with cellulitis, highlighting a diagnostic challenge for clinicians, according to a case study published by Cureus.
The case involved a 76-year-old male with a history of hypertension and chronic kidney disease who presented with erythema, edema and warmth in his left lower leg. Initial assessment led to a diagnosis of cellulitis, and the patient was started on intravenous antibiotics. However, the patient’s condition did not improve with antibiotic treatment, prompting further investigation.
Dermatological examination revealed hyperpigmentation, lipodermatosclerosis, and venous ectasia consistent with stasis dermatitis. An “id” reaction, characterized by a widespread eruption of small, itchy papules, was also observed. This reaction, occurring distantly from the initial site, further complicated the clinical picture and initially obscured the correct diagnosis.
The patient’s history of chronic venous insufficiency was a key factor in the eventual diagnosis. Stasis dermatitis develops due to prolonged venous hypertension, leading to inflammation and skin changes in the lower legs. The id reaction is a type IV hypersensitivity reaction triggered by antigens released from the affected skin, causing a more generalized inflammatory response.
The antibiotics were discontinued, and the patient was transitioned to a treatment plan focused on managing the stasis dermatitis, including compression therapy and topical corticosteroids. The id reaction subsided with treatment, and the patient’s leg symptoms gradually improved.
The case underscores the importance of considering alternative diagnoses when patients do not respond to standard treatments. A similar case published in Cureus detailed disseminated autoeczematization secondary to cellulitis, further illustrating the potential for misdiagnosis in inflammatory skin conditions. The authors of the stasis dermatitis case study emphasize the require for a thorough dermatological evaluation and consideration of underlying venous disease in patients presenting with lower extremity inflammation.
The patient remains under observation for recurrence of stasis dermatitis and management of his underlying chronic conditions.
