ABSTRACT
Mucha-Habermann disease, or Pityriasis Lichenoides et Varioliformis Acuta (PLEVA), is a rare dermatological illness marked by the abrupt emergence of reddish-brown papules, some of which may develop into necrotic lesions. Misdiagnosis of PLEVA can lead to unnecessary treatments and adverse symptoms.
A 13-year-old boy was receiving ongoing scabies treatment. He came to the hospital with worsening skin lesions and systemic symptoms like headaches, weakness, and a burning sensation in the affected areas. Examining his arms, thighs, and trunk revealed lesions at different phases of development, such as tiny papules, vesicles, and necrotic-crusted patches. The diagnosis was confirmed by a skin biopsy that showed perivascular lymphocytic inflammation, spongiosis, and parakeratosis—all of which are characteristic characteristics of PLEVA. The patient's condition was made worse by the misdiagnosis and prolonged scabies treatment, which also resulted in excruciating itchiness. Erythromycin, triamcinolone, antihistamines, and topical steroids were provided to the patient. Significant progress was seen after two weeks, and the active lesions disappeared in a month, leaving behind varioliform scars and patches with changed pigmentation.
This case underscores how crucial it is to make an appropriate diagnosis when a patient presents with a chronic or uncommon dermatological illness. In addition to delaying required treatment, misdiagnosing PLEVA as a more prevalent illness, like scabies, can cause needless difficulties and patient suffering.
Key words: Pityriasis Lichenoides et Varioliformis Acuta, Mucha-Habermann disease, post-treatment scabies pruritus, Pityriasis Lichenoides Chronica.
