Lymphoma is a cancer of the lymphatic system that can arise from either B-cells or T-cells. It is the fourth most common cancer in the UK, with incidence of non-Hodgkin lymphoma increasing. Various viruses and diseases can predispose individuals to developing lymphoma. Clinical manifestations vary between patients but commonly include lymphadenopathy, fever, night sweats, and weight loss. Diagnosis requires a biopsy for examination under microscope. Staging involves CT, PET, or MRI scans to determine spread. The liver, spleen, and lymph nodes are most frequently involved organs. Sonography may reveal hypoechoic lesions in the liver or other organs.Cardiac tumours
Cardiac tumoursAnkur Batra

Primary cardiac tumors are rare but can involve the heart directly or through metastasis. Benign tumors like myxomas are the most common primary cardiac tumors and often present with nonspecific symptoms of obstruction, embolism, or constitutional effects. Myxomas typically occur in the left atrium of middle-aged women and can be part of Carney syndrome, characterized by extracardiac tumors and skin pigmentation. Echocardiography is the primary diagnostic tool used to identify location and characteristics of a suspected cardiac tumor.Understanding the thymus

Anatomy of the Larynx
Larynx is a cartilaginous structure located in the **anterior neck** at the level of **C3C6 vertebrae**.
* Also called the **voice box**responsible for **phonation**, **airway protection**, and **breathing regulation**.
**Cartilages of the Larynx**
**Unpaired Cartilages:**
1. **Thyroid cartilage**:
* Largest cartilage; forms the **Adams apple (laryngeal prominence)**.
* Composed of two laminae that fuse anteriorly.
2. **Cricoid cartilage**:
* Ring-shaped; **only complete ring** around the airway.
* Located below thyroid cartilage; articulates with thyroid & arytenoid cartilages.
3. **Epiglottis**:
* Leaf-shaped elastic cartilage.
* Covers the laryngeal inlet during swallowing.
**Paired Cartilages:**
1. **Arytenoid**:
* Pyramid-shaped; sit on top of cricoid.
* Attach vocal cords and muscles.
2. **Corniculate**:
* Small cartilages sitting atop the arytenoids.
3. **Cuneiform**:
* Embedded in the aryepiglottic folds; provide structural support.
**Intrinsic Muscles of the Larynx**
> Responsible for controlling **vocal cord movement**.
| Muscle | Action | Nerve Supply |
| **Cricothyroid** | Tenses vocal cords | External laryngeal nerve |
| **Thyroarytenoid** | Relaxes vocal cords | Recurrent laryngeal nerve |
| **Posterior cricoarytenoid** | Abducts vocal cords (opens glottis) | Recurrent laryngeal nerve |
| **Lateral cricoarytenoid** | Adducts vocal cords | Recurrent laryngeal nerve |
| **Transverse & oblique arytenoids** | Closes the posterior glottis | Recurrent laryngeal nerve |
| **Vocalis** | Fine-tunes pitch | Recurrent laryngeal nerve | **Nerve Supply*
* **Motor**:
* All intrinsic muscles (except cricothyroid): **Recurrent laryngeal nerve** (branch of vagus nerve).
* Cricothyroid: **External branch of superior laryngeal nerve**.
* **Sensory**:
* Above vocal cords: **Internal branch of superior laryngeal nerve**.
* Below vocal cords: **Recurrent laryngeal nerve**.
**Blood Supply**
* **Superior laryngeal artery** (branch of superior thyroid artery).
* **Inferior laryngeal artery** (branch of inferior thyroid artery).
**Laryngeal Cavity & Folds**
Divided into 3 regions:
1. **Vestibule** from inlet to vestibular folds (false cords).
2. **Ventricle** between vestibular and vocal folds.
3. **Infraglottic cavity** below vocal cords to trachea.
**Vocal folds (true cords)** involved in sound production.INTERPRETATION OF LABORATORY INVESTIGATIONS.pptx
