1. Iron-deficiency anemia
2. Intermittent, painless post-cricoid dysphagia, initially most noticeable with solid foods
3. A thin upper esophageal web, usually anterior and in the cervical or post-cricoid esophagus

Etiology of Plummer-Vinson syndrome

• Iron deficiency impairs epithelial and muscle-cell function in the mouth, pharynx, and upper esophagus.
• This promotes mucosal atrophy, inflammation, reduced mucosal repair, and possibly impaired swallowing motility.
• Over time, these changes contribute to formation of a thin post-cricoid/upper-esophageal web and cause dysphagia.

Why does the iron-deficiency anemia occur?

• Chronic menstrual blood loss, especially heavy menstrual bleeding in premenopausal women
• Chronic gastrointestinal blood loss, for example from peptic ulcer disease, gastritis, colorectal lesions, vascular lesions, or malignancy
• Reduced iron absorption, especially with celiac disease, inflammatory bowel disease, autoimmune atrophic gastritis, H. pylori infection, or after some bariatric operations
• Inadequate dietary intake, usually alongside increased requirements or loss
• Less commonly, other chronic blood loss or increased requirements such as pregnancy

What happens when cancer develops?

• Post-cricoid hypopharynx
• Proximal/cervical esophagus
• Sometimes the oral cavity or pharynx

Typical cancer-stage presentation

• Progressive dysphagia, often worsening from solids to semisolids and liquids
• Odynophagia: painful swallowing
• Unintentional weight loss or reduced oral intake
• Persistent throat or neck discomfort
• Referred ear pain, often unilateral, despite a normal ear examination
• Hoarseness or voice change, particularly with laryngeal involvement
• Persistent cough, aspiration, or choking
• A neck mass, due to cervical lymph-node metastasis
• Occasionally bleeding, anemia worsening, or persistent foul breath

1. Immediate priorities: admit and secure the airway plan

Assess immediately

• Work of breathing, respiratory rate, oxygen saturation, ability to speak full sentences
• Stridor, muffled voice, drooling, inability to handle secretions, orthopnea, cyanosis, agitation, exhaustion
• Flexible nasoendoscopy at bedside, if she is stable and this can be done by an experienced ENT clinician, to assess:
  • Supraglottis, glottis, pyriform fossae, post-cricoid region
  • Laryngeal inlet narrowing
  • Vocal-cord mobility/fixity
  • Pooling of secretions and aspiration risk
• Review the CECT with ENT/radiology: exact degree and level of airway compromise, cartilage invasion, prevertebral involvement, carotid encasement, nodal disease, and whether a retropharyngeal collection is possible.

Airway action

• Have a difficult-airway plan before any biopsy, endoscopy, sedation, or general anesthetic.
• If there is stridor, significant narrowing, worsening dyspnea, inability to clear secretions, or an unsafe airway on endoscopy/CT, the patient may need an urgent awake tracheostomy, performed by the experienced ENT team.
• Avoid casually sedating the patient or attempting repeated conventional intubation. A mass at the post-cricoid/hypopharyngeal level can turn a partially compensated airway into a complete obstruction.
• If the patient acutely deteriorates: activate the emergency airway pathway immediately. Do not delay airway management for staging tests.

2. Establish a tissue diagnosis

1. Examination under anesthesia with direct laryngoscopy, hypopharyngoscopy, and upper esophagoscopy
   • Define the upper and lower tumor extent.
   • Inspect pyriform sinuses, posterior pharyngeal wall, post-cricoid area, larynx, and cervical esophagus.
   • Assess for a synchronous upper-aerodigestive tract lesion.
2. Multiple deep biopsies from the primary lesion for histopathology.
   • Most likely diagnosis is squamous cell carcinoma of the hypopharynx/post-cricoid region or cervical esophagus.
   • Request pathology to confirm histologic type and grade. Immunohistochemistry is guided by morphology if a non-squamous malignancy is suspected.
3. Ultrasound-guided FNAC or core biopsy of an accessible cervical node can provide diagnosis and may be safer or quicker than manipulating a very obstructive primary lesion.

3. Staging work-up

Local and regional staging

• Thorough head-and-neck examination and flexible laryngoscopy documentation.
• Review the existing contrast-enhanced CT neck and chest.
• MRI neck if there is uncertainty about:
  • Prevertebral fascia or vertebral involvement
  • Laryngeal/cartilage invasion
  • Soft-tissue extension
  • Retropharyngeal nodal disease
• Neck ultrasound with FNAC/core biopsy of suspicious nodes, if not already sampled.

Distant disease and second-primary assessment

• FDG PET-CT for stage III-IV disease, especially before committing to major curative surgery or definitive chemoradiation. It helps identify distant metastases and synchronous lesions.
• CT chest is essential if PET-CT is unavailable.
• Consider bronchoscopy and full upper-GI assessment as clinically indicated, particularly because the lesion extends into the cervical esophagus and field cancerization/synchronous primaries can occur.

Baseline pre-treatment assessment

• CBC with indices, ferritin, transferrin saturation, reticulocyte count.
• Renal function, electrolytes, liver function, albumin, glucose, coagulation profile.
• Correct dehydration, electrolyte derangement, and severe anemia.
• Nutritional assessment: weight loss percentage, BMI, dietary intake, swallowing safety, sarcopenia.
• Dental assessment before radiotherapy.
• Audiogram and renal assessment if cisplatin is being considered.
• Speech-language pathology evaluation for swallowing, aspiration risk, and expected functional outcomes.
• Performance status, comorbidities, smoking and alcohol history.

4. Nutrition and supportive measures now

• Keep oral intake limited or nil if aspiration/airway risk is substantial.
• IV fluids, electrolyte correction, antiemetic treatment if needed.
• Urgent dietitian and speech-language therapist review.
• Choose enteral access with the treating surgical/oncology team:
  • Short-term nasogastric/nasojejunal feeding may be possible in selected cases but may be impractical or unsafe with a tight upper lesion.
  • Gastrostomy or jejunostomy is often considered when prolonged support is anticipated.
• Treat iron-deficiency anemia, but do not assume it explains the mass or allow iron therapy to delay oncologic work-up.
• Smoking and alcohol cessation support.

5. Definitive treatment depends on resectability and stage

A. Resectable disease, especially if there is major laryngeal/airway involvement

• Total laryngopharyngectomy or pharyngolaryngectomy
• Resection of involved cervical esophagus, if necessary
• Bilateral or appropriate therapeutic neck dissection
• Reconstruction with free flap, free jejunal transfer, gastric pull-up, or another reconstructive option depending on defect extent
• Postoperative radiotherapy, with concurrent chemotherapy if high-risk pathology is present, particularly positive margins or extranodal extension

B. Organ-preservation approach

• Definitive concurrent chemoradiation, commonly cisplatin-based if the patient is fit
• Alternative systemic regimens if cisplatin is unsuitable
• Response-adapted or induction approaches only in selected cases and within an experienced tumor-board pathway
• Salvage surgery for persistent or recurrent local disease, if feasible

C. Unresectable metastatic disease or unfit for curative therapy

• Systemic therapy, possibly including immunotherapy depending on pathology and biomarker assessment
• Palliative radiotherapy for local symptoms, bleeding, pain, or obstruction
• Durable airway and feeding access
• Early palliative-care involvement alongside oncology, not only at end of life

Practical summary for this patient

1. Admit urgently.
2. ENT and anesthetic difficult-airway assessment immediately.
3. Secure the airway first if there is meaningful compromise, often with controlled awake tracheostomy when indicated.
4. Obtain endoscopic biopsy or node biopsy for diagnosis.
5. Complete CT/MRI plus PET-CT staging, with full nodal and distant-metastasis evaluation.
6. Correct dehydration, anemia, and malnutrition, and establish safe nutrition.
7. Present to a head-and-neck cancer multidisciplinary team to choose between radical surgery with reconstruction and adjuvant treatment versus definitive chemoradiation.
