|-
| style="background: #DCDCDC; padding: 5px;" |[[Impetigo]] 
|
*It commonly presents with pimple-like lesions surrounded by [[erythematous]] [[skin]]. Lesions are [[pustules]], filled with [[pus]], which then break down over 4-6 days and form a thick crust. It's often associated with insect bites, cuts, and other forms of [[trauma]] to the [[skin]].
|-
| style="background: #DCDCDC; padding: 5px;" |[[Insect bite]]s
|
* The insect injects [[formic acid]], which can cause an immediate [[skin]] reaction often resulting in a [[rash]] and swelling in the injured area, often with formation of [[vesicles]].
|-
| style="background: #DCDCDC; padding: 5px;" |[[Kawasaki disease]]
|
* Commonly presents with high and persistent [[fever]], red [[mucous membranes]] in mouth, "[[strawberry tongue]]", [[swollen lymph nodes]] and [[skin rash]] in early disease, with peeling off of the [[skin]] of the [[hands]], [[feet]] and [[genital area]].
|-
| style="background: #DCDCDC; padding: 5px;" |[[Measles]]
|
* Commonly presents with high [[fever]], [[coryza]] and [[conjunctivitis]], with observation of [[oral mucosa|oral mucosal]] lesions ([[Koplik's spots]]), followed by widespread [[skin rash]].
|-
| style="background: #DCDCDC; padding: 5px;" |[[Monkeypox]]
|
* The presentation is similar to [[smallpox]], although it is often a milder form, with [[fever]], [[headache]], [[myalgia]], [[back pain]], [[swollen lymph nodes]], a general feeling of discomfort, and exhaustion. Within 1 to 3 days (sometimes longer) after the appearance of [[fever]], the patient develops a papular [[rash]], often first on the face. The lesions usually develop through several stages before crusting and falling off.
|-
| style="background: #DCDCDC; padding: 5px;" |[[Rubella]]
|
* Commonly presents with a facial [[rash]] which then spreads to the [[trunk]] and [[limbs]], fading after 3 days, low grade [[fever]], swollen [[glands]], [[joint pain]]s, [[headache]] and [[conjunctivitis]]. The [[rash]] disappears after a few days with no staining or peeling of the [[skin]]. ''[[Forchheimer's sign]]'' occurs in 20% of cases, and is characterized by small, red [[papules]] on the area of the [[soft palate]].
|-
| style="background: #DCDCDC; padding: 5px;" |Atypical [[measles]]
|
* The symptoms commonly begin about 7-14 days after infection and present as [[fever]], [[cough]], [[coryza]] and [[conjunctivitis]]. Observation of [[Koplik's spots]] is also a characteristic finding in measles.
|-
| style="background: #DCDCDC; padding: 5px;" |[[Coxsackievirus]]
|
* The most commonly caused disease is the [[Coxsackie A]] disease, presenting as ''hand, foot and mouth disease''. It may be [[asymptomatic]] or cause mild [[symptoms]], or it may produce [[fever]] and painful [[blisters]] in the mouth ([[herpangina]]), on the palms and fingers of the hand, or on the soles of the feet. There can also be [[blisters]] in the [[throat]]  or above the [[tonsils]]. Adults can also be affected. The [[rash]], which can appear several days after high temperature and painful sore throat, can be itchy and painful, especially on the hands/fingers and bottom of feet.
|-
| style="background: #DCDCDC; padding: 5px;" |[[Acne]]
|
* It is typical of teenagers, usually appears on the [[face]] and upper neck, but the [[chest]], [[human back|back]] and [[shoulder]]s may have [[acne]] as well. The upper [[arm]]s can also have [[acne]], but lesions found there are often [[keratosis pilaris]], not [[acne]]. The typical [[acne]] lesions are [[comedones]] and [[inflammatory]] [[papules]], [[pustules]], and [[nodules]]. Some of the large [[nodules]] were previously called "[[cyst]]s"
|-
| style="background: #DCDCDC; padding: 5px;" |[[Syphilis]]
|It commonly presents with gneralized systemic [[symptoms]] such as [[malaise]], [[fatigue]], [[headache]] and [[fever]]. [[Skin]] eruptions may be subtle and [[asymptomatic]] It is classically described as:
* Non-pruritic bilateral symmetrical mucocutaneous [[rash]]
* Non-tender regional [[lymphadenopathy]]
* Condylomata lata and
* Patchy [[alopecia]].
|-
| style="background: #DCDCDC; padding: 5px;" |[[Molluscum contagiosum]]
|
* The lesions are commonly flesh-colored, dome-shaped, and pearly in appearance. They are often 1-5 millimeters in diameter, with a dimpled center. Generally not painful, but they may itch or become irritated. Picking or scratching the lesions may lead to further [[infection]] or scarring. In about 10% of the cases, [[eczema]] develops around the lesions. They may occasionally be complicated by secondary [[bacterial infections]].
|-
| style="background: #DCDCDC; padding: 5px;" |[[Mononucleosis]]
|
* Common [[symptoms]] include low-grade [[fever]] without [[chills]], [[sore throat]], white patches on [[tonsils]] and back of the throat, [[muscle weakness]] and sometime extreme [[fatigue]], tender [[lymphadenopathy]], [[petechial hemorrhage]] and [[skin rash]].
|-
| style="background: #DCDCDC; padding: 5px;" |Toxic [[erythema]]
|
* It is a common [[rash]] in infants, with clustered and [[vesicular]] appearance.
|-
| style="background: #DCDCDC; padding: 5px;" |[[Rat-bite fever]]
|
* It commonly presents with [[fever]], [[chills]], open sore at the site of the bite and [[rash]], which may show red or purple plaques.
|-
| style="background: #DCDCDC; padding: 5px;" |[[Parvovirus B19]]
|

|
* It commonly includes [[fever]], punctate red [[macules]] on the hard and soft [[palate]] and [[uvula]] ([[Forchheimer's spots]]), bright red [[tongue]] with a "strawberry" appearance, [[sore throat]] and [[headache]] and [[lymphadenopathy]].
|-
| style="background: #DCDCDC; padding: 5px;" |[[Rocky Mountain spotted fever]]
|
* The [[symptoms]] may include [[maculopapular rash]], [[petechial rash]], [[abdominal pain]] and [[joint pain]].
|-
| style="background: #DCDCDC; padding: 5px;" |[[Stevens-Johnson syndrome]]
|
* The [[symptoms]] may include [[fever]], [[sore throat]]  and [[fatigue]]. Commonly presents [[ulcers]] and other lesions in the [[mucous membranes]], almost always in the [[mouth]] and lips but also in the genital and anal regions. Those in the mouth are usually extremely painful and reduce the patient's ability to eat or drink. [[Conjunctivitis]] of the eyes occurs in about 30% of children. A [[rash]] of round lesions about an inch across, may arise on the face, trunk, arms and legs, and soles of the feet, but usually not on the scalp.
|-
| style="background: #DCDCDC; padding: 5px;" |[[Varicella-zoster virus]]
|
* It commonly starts as a painful [[rash]] on one side of the face or body. The [[rash]] forms blisters that typically scab over in 7-10 days and clears up within 2-4 weeks.
|-
| style="background: #DCDCDC; padding: 5px;" |[[Chickenpox]]
|
* It commonly starts with [[conjunctival]] and catarrhal [[symptoms]] and then characteristic spots appearing in two or three waves, mainly on the body and head, rather than the hands, becoming itchy raw pox (small open sores which heal mostly without scarring). Touching the fluid from a [[chickenpox]] blister can also spread the disease.
|-
| style="background: #DCDCDC; padding: 5px;" |[[Meningococcemia]]
|
* It commonly presents with [[rash]], [[petechiae]], [[headache]], [[confusion]], and [[stiff neck]], high [[fever]], mental status changes, [[nausea]] and [[vomiting]].

|
* The first [[symptom]] is commonly a bump formed by a mite-bite, eventually resulting in a black, crusty scab. Many of the [[symptoms]] are [[flu]]-like including [[fever]], [[chills]], [[weakness]] and [[muscle pain]] but the most distinctive [[symptom]] is the [[rash]] that breaks out, spanning the person's entire body.
|-

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] 

Histoplasmosis
[9][10][11][12]

Penicillium marneffei[13]
Condyloma acuminatum [14]

Pyogenic granuloma[15][16][17]

Langerhans cell histiocytosis[18][19][20][21][22]

Basal cell carcinoma[23]

Amelanotic melanoma
