I now have enough information to give a comprehensive clinical answer. Let me compile it.
Clinical Assessment: 4-Year-Old with Right Cheek Swelling (14 Days), No Fever
The image shows a child with a relatively symmetric face clinically, but the history of 14 days of unilateral right cheek swelling without fever, headache, vomiting, or dysphagia is the key differentiator.
Differential Diagnoses
The swelling without fever (afebrile), without systemic symptoms, and lasting 14 days narrows the differential considerably. Using the WashU framework, this falls under "nonprogressive" or "slowly progressive" swelling in a child.
1. Parotid Gland Pathology
| Condition | Key Features | Fits this Case? |
|---|---|---|
| Mumps (viral parotitis) | Bilateral > unilateral, fever, tender, MMR unvaccinated | Possible if unilateral presentation (occurs in ~20%) and fever absent/resolved |
| Recurrent parotitis of childhood | Recurrent unilateral parotid swelling, afebrile between episodes, age 3-6 years | Strong fit |
| Parotid hemangioma/vascular malformation | Soft, compressible, slow-growing, afebrile | Possible |
| HIV-associated parotitis | Bilateral cystic, exposure history, chronic | Less likely |
2. Lymphadenopathy (Most Common Cause)
| Condition | Key Features |
|---|---|
| Reactive lymphadenopathy | Post-URTI, soft, mobile nodes in parotid/pre-auricular region |
| Non-tuberculous mycobacterial (NTM) lymphadenitis | Unilateral, firm, slow-growing, afebrile, 1-5 year age group - classic fit |
| Tuberculous lymphadenitis | Slower growing, matted nodes, contact history |
| Lymphoma (NHL/Hodgkin) | Progressive, rubbery firm, systemic B symptoms |
3. Dental/Odontogenic Origin
| Condition | Key Features |
|---|---|
| Buccal space abscess | Usually with fever, pain, dental caries; may be subacute |
| Periapical abscess with minimal signs | Possible if chronic/walled off |
4. Benign Tumors/Cysts
| Condition | Key Features |
|---|---|
| Dermoid cyst | Smooth, painless, slowly growing |
| Lymphatic malformation | Soft, transilluminates, congenital |
| Pleomorphic adenoma (parotid) | Rare in this age, painless |
5. Malignant (Must Not Miss)
| Condition | Key Features |
|---|---|
| Rhabdomyosarcoma (RMS) | Can present in 3-5 year olds with rapidly progressive facial swelling - a 4-year-old with facial swelling is a classic presentation |
| Parotid malignancy | Rare, facial nerve involvement |
Most Likely Diagnoses in This Child
Given: age 4 years, afebrile, right cheek, 14 days, no systemic symptoms:
- Non-tuberculous mycobacterial (NTM) lymphadenitis - top differential in this age group, classically afebrile unilateral cervicofacial swelling
- Recurrent parotitis of childhood - age and presentation match perfectly (Scott-Brown's Otorhinolaryngology, p.488)
- Reactive lymphadenopathy (post-viral)
- Mumps - if not fully vaccinated (can be afebrile in ~20% cases)
- Rhabdomyosarcoma - must be excluded if progressive
Investigations
- FBC + CRP/ESR - baseline inflammation
- Serum amylase/lipase - elevated in parotitis
- Mumps IgM/IgG serology (and MMR vaccination history)
- Mantoux/IGRA + CXR - if TB suspected
- Ultrasound of cheek/parotid - first-line imaging; characterizes whether the swelling is in the parotid gland, a lymph node, or a cyst; looks for internal architecture (cystic vs solid)
- CECT face and neck - if abscess suspected or malignancy to be excluded
- Sialography or MRI parotid - if recurrent parotitis suspected
Management by Diagnosis
Recurrent Parotitis of Childhood
- Mainly supportive: adequate hydration, sour candy/lemon drops (stimulates saliva flow), warm compresses, NSAIDs for pain
- Antibiotics (amoxicillin-clavulanate) only if secondary bacterial infection suspected
- Tends to resolve spontaneously at puberty
NTM Lymphadenitis
- Surgical excision is treatment of choice (curative in >95%)
- Clarithromycin-based antibiotic regimen if surgery not possible
- Do NOT incise (leads to chronic fistula)
Mumps
- No specific antiviral treatment - self-limiting condition
- Supportive: rest, hydration, antipyretics (ibuprofen/paracetamol), soft diet
- Isolation for 5 days from onset of parotid swelling (Scott-Brown's Otorhinolaryngology)
- Ensure MMR vaccination of contacts
Reactive Lymphadenopathy
- Observation for 4-6 weeks if benign features on USS
- No antibiotics unless bacterial cause confirmed
Odontogenic Abscess
- Amoxicillin-clavulanate + dental referral
- Surgical drainage if fluctuant
RMS (if suspected)
- Urgent oncology referral
- Staging workup (MRI, CT chest/abdomen, bone marrow biopsy)
- Multimodal treatment: chemotherapy + radiotherapy ± surgery
Red Flags Requiring Urgent Workup
- Rapidly progressive swelling
- Facial nerve palsy
- Skin fixity or discoloration overlying mass
- Trismus, dysphagia
- Systemic B symptoms (weight loss, night sweats)
- Hard, fixed, non-tender mass
Recommended immediate next step: Ultrasound of the right cheek/parotid region + FBC/CRP + MMR vaccination history to narrow the differential before initiating treatment.
