Overview

Molluscum contagiosum must be differentiated from other diseases that cause inflammatory or ulcertive skin , genital, or mucosal lesions including chicken pox, herpes zoster, erythema multiforme, cryptococcosis, histoplasmosis, pyogenic granuloma.

Differential Diagnosis

Different conditions that cause a round papular rash must be differentiated from molluscum contagiosum based on the appearance of the lesions such as:^[1]^[2]^[3]^[4]^[5]^[6]^[7]

Disease	Features	Images
Molluscum contagiosum	Skin papules: Firm Dome shaped Shiny 2 to 5 mm diameter May have central indentation or umbilication Polypoid lesion: Occasionally, with a stalk-like base Visibly inflamed lesions occasionally may be seen Diffuse erythema: May be seen due to Gianotti-Crosti like eruptions
Cryptococcosis^[8]	Caused by encapsulated yeast (fungus) Cryptococcus neoformans May be completely asymptomatic May have latent infection or symptomatic disease Pneumonia-like illness with fever, cough, sputum production and chest pain May lead to: Meningoencephalitis
Histoplasmosis ^[9]^[10]^[11]^[12]	Acquired via inhalation of airborne microconidia Can present with: Acute pulmonary histoplasmosis presenting with fever, cough and dyspnea Skin rash Symmetrical joint pain Disseminated histoplasmosis presents with: Sepsis Acute respiratory distress syndrome Disseminated intravascular coagulation
Penicillium marneffei^[13]	Fever Skin lesions Anemia Generalized lymphadenopathy Hepatomegaly
Condyloma acuminatum ^[14]	Occur in clusters May be very tiny May spread into large masses in the genital or penis area
Pyogenic granuloma^[15]^[16]^[17]	A vascular lesion occurs on both mucosa and skin Appears as an overgrowth of tissue due to irritation, physical trauma or hormonal factors Involve the gums, the skin and nasal septum, and has also been found far from the head such as in the thigh
Langerhans cell histiocytosis^[18]^[19]^[20]^[21]^[22]	Result of either a true neoplastic process or a reactive immune condition. Common symptoms of Langerhans cell histiocytosis include: Bone pain Rash Fever Failure to thrive Scaly erythematous lesions located on the scalp and extremities Localized bone tenderness Hepatosplenomegaly
Basal cell carcinoma^[23]	Skin growths on sun-exposed skin Ulcerative pupils
Amelanotic melanoma	Amelanotic or hypomelanotic lesions or maybe nodular and desmoplastic subtypes Lesions may present as pink or red macules, plaques, or nodules, often with well-defined borders Often clinically confused with benign lesions
