CASE STUDY: LYMPHOMA/ GRANULOMATOUS DISEASE
HISTORY
• 12 April 2012• 36 year old female (black)• Referred to Surgery department from private GP
• RVD + on ART since 13/01/2012 (EFV, TDF, Lamivudine)• PTB on treatment since 19/03/2012
• Presents with:• Right neck mass• Started as small lump 2 months ago• Progressing in size• Painful
CLINICAL EXAM
• Large solid mass • Extending from right earlobe to angle of jaw• Not mobile• No bruit• No fluctuance• Smaller lympnodes right cervical area
• PROBLEM LIST:• Enlarging mass in upper cervical region (?lymphoma)
• Plan: Ultrasound then TRUCUT
INCISIONAL BIOPSY
• 19 April 2012• Wedge incision made into mass in posterior triangle of
neck• Skin closed with sub-cuticular monocryl sutures• No complications• Discharged following day
• Plan:• F/U in 2 weeks for results
• 29 May 2012• CT scan
SPACES INVOLVED
Parotid space• Parotid gland; Lympnodes• CN VII; retro-mandibular vein, ECA
Masticator space• Masseter, Pterygoid and temporalis muscle• CN V3; venous plexus and mandible
Parapharyngeal space• Fat, deep cervical lympnodes and paraganglia• Maxillary art• Lingual/inferior alveolar/auriculo-temporal nerve.

HISTOLOGY RESULTS
• 23 May 2012• Microscopy• Fibro-fatty tissue; muscle and tumor • Atypical cells
• large hyperchromatic nuclei• Scanty eosinophilic cytoplasm• Prominent nuclear polymorphism
• Tumor infiltrate skeletal muscle
• Immuno-histochemical stains• CK/AE13 and MNF116 - Negative (Carcinomas)• CD3 - Negative (T cell origin)• CD20/10 - Positive (B cell origin)• Ki67 - Positive (80%) (Mitotic activity)
DIAGNOSIS:
LARGE B-CELL LYMPHOMA
OUTCOME
• 31 May 2012• (Parotid tumor?)• No infiltration of bone• Cervical and axillary
lympnodes
• PLAN:• Theatre on 07/08/2012• superficial
parotidectomy • cervical dissection
• Missed theatre date!
• September 2012• Mass still enlarging• Tender• Not mobile
• PLAN:• Repeat CT• Surgery on 16/10/2012
