Physical Examination
The patient had a diffuse, erythematous papular rash on his
trunk and groin. Overlying areas of linear excoriations were
noted as well on the trunk and folds of the groin. Very dis-
crete linear burrows were also seen between the interdigital
spaces of his right and left hands.
Clinical Differential Diagnosis
• Insect bites
• Atopic Dermatitis
• Neurotic Excoriations
• Scabies
• Drug Reaction
Histopathology
Spongiotic epidermal changes with marked mixed perivascu-
lar and interstitial inflammatory cells of lymphocytes, histio-
cytes, abundant eosinophils and occasional neutrophils are
present (Fig. 1.1).
Hyperkeratosis and parakeratosis with neutrophils are
seen in the stratum corneum. Organisms and material mor-
phologically consistent with scabies and scabies products are
identified (Figs. 1.2 and 1.3).
In addition, PAS stain reveals fungal hyphae in the in the
stratum corneum (Fig. 1.4).
Final Diagnosis
–– Scabies infestation.
–– Dermatophytosis.
