1. Pediatric Neck Masses Jaime J. Rueda
July 24-29, 2006
Med-Peds Clinic conference
2. Background In adults, 80% of neck masses are neoplastic and 80% of these are malignant
Versus in kids, 90% of neck masses are benign
Most common= lymphadenitis
3. Miss A.S. Case: Miss A.S. is a 3 year old female who presents with a 1 week h/o a palpable neck mass.
Pertinent history and physical?
Types of neck masses?
Indications for referral?
4. History and Physical Age, location, physical characteristics, growth
Associated sx: fever, wt. loss, night sweats, fatigue, sore throat
Travel hx, exposure to people at risk for Tb, immunocompromised, cat scratches/bites
PE: size, tender, erythematous, moves with swallowing/tongue protrusion, unilateral/bilateral, drainage
6. Types of masses Inflammatory
Cervical lymphadenopathy
Suppurative lymph nodes (lymphadenitis)
Granulomatous disease
Congenital
Thyroglossal duct cysts
Branchial apparatus cysts
Lymphangiomas (cystic hygromas)
Hemangiomas
Neoplasms (Benign and malignant)
Lymphoma
7. Inflammatory masses Cervical lymphadenopathy
Palpable cervical nodes in 40% of infants
Nodes <3mm and cervical nodes =1cm in diameter in <12 year olds are normal.
Suppurative lymph nodes (lymphadenitis)
Caused by -hemolytic strep and S. aureus
Usually tender, fluctuant, erythematous, swollen
If unilat, pyogenic infection in pharynx and tonsils but if bilateral, viral
EBV(Mono) vs. CMV
8. Granulomatous disease Atypical mycobacterium TB
Chronic lymph node infections in kids(1-5 yo)
Enters body through breaks in mucous membranes, e.g. teeth eruption
Chronic, unilateral, firm masses in the submandibular or preauricular regions
Dx: FNA, surgical excision, PPD?
Tx: Azithromycin
Cat Scratch Disease
Etiology: Bartonella Henselae
H/o exposure to cat, tender regional LAD, 1 inoculation site
Dx: Hx, Bartonella titers
Tx: Azithromycin, Bactrim, Rifampin
9. Congenital Masses Thyroglossal duct cysts
Vestigial remnants of embryonic thyroglossal duct
Located subhyoid, midline or just lateral to it
Retreats with tongue protrusion/swallowing
Dx: CT, u/s, thyroid scan
Tx: Sistrunk procedure
10. Congenital masses continued Branchial apparatus(BA) cyst, fistula, sinus
Remnants of fetal BA
90% from 2nd BA
Cyst: Slowly enlarging, lateral cervical mass near ant. to middle 1/3 of SCM
Round, smooth, mobile, nontender
Dx & Tx: CT and abx if inflamed and surgery
11. Congenital masses continued Lymphangioma (Cystic hygroma)
Lateral cervical region along jugular chain of lymphatics
65% soft, painless, compressible at birth
? size with valsalva, transilluminates
May impinge airway, thus requiring surgery
Hemangioma
30% at birth? ? size in 1st yr
Soft, mobile, bluish hue, no transillumination, ? size with valsalva
~90% resolve spont by 7 yo.
12. Neoplasms Lymphoma
Neck mass is presenting sign in 80% children with Hodgkins disease and 40% with non-Hodgkins(NHL)
NHL: extranodal, more widespread, more common in <5 yo
Charac: large, firm, mobile masses in posterior cervical triangle or supraclavicular area. Assoc. with B sx: fever>38 C, wt. loss of 10%, and night sweats
13. Indications for referral Mass does not resolve with 2 wk course of abx
Malignant tumor suspected
Rapidly enlarging mass without inflammation
Mass in thyroid/ parotid gland
Fixed mass
Matted cervical lymph nodes
14. Conclusions Pediatric neck masses are common reasons for primary care visits that are mostly benign.
Some have characteristic features on history and physical exam that aid in diagnosis
Can be separated into 3 categories: inflammatory, congenital and Neoplastic
Referral is indicated when antibiotics do not decrease the size of the mass or one suspects malignancy
Follow up: A.S. had positive Bartonella IgG titer. She was treated with Azythromycin*3 days, and the size of the nodules have since decreased.
