    1. Why the man appreance puffy face ?

    Swelling of the face (face oedema) which may develop if a tumour presses on a main veincoming towards the heart from the head or ablockage of a main blood vessel (superior

    vena cava obstruction).

    The leading symptoms of SVC syndromeare facial edema, distended veins in the neck and

    sometimes chest, arm edema, shortness of breath, cough, facial plethora/fullness, and less

    commonly wheezing, lightheadedness, headaches, and even confusion.

    2. Why he has hoarse voices ?

    Sound is produced in the larynx by vibration of the vocal cords. Resonance occurs in the pharynx, nose and

    mouth; articulation uses the mouth and tongue. Coughing requires adduction of the vocal cords to be effective.

    Innervation of the laryngeal muscles is from the vagus nerve via its branches, the superior laryngeal andrecurrent laryngeal nerves. The recurrent laryngeal nerve controls abduction and adduction of the vocal

    cords. This nerve has a long course, from the base of the skull to the mediastinum: on the left side it loops under

    the aortic arch and on the right under the subclavian artery.

    The vocal cords are subject to high forces and so are vulnerable to voice overuse or misuse.

    The anorexia/cachexia syndrome is a multi-factorial entity. While the association between

    contributing factors is not clearly understood, chronic inflammation has been identified as a core

    mechanism. Lipolysis, muscle protein catabolism, increases in acute-phase proteins (including C-

    reactive protein), and a rise in pro-inflammatory cytokines (notably IL-1 [interleukin-1], IL-6

    [interleukin-6], TNF [tumor necrosis factor alpha], and LIF [leukemia inhibitory factor]) are

    associated with the syndrome and are similar to the processes and substances found in the metabolicresponse to an acute injury.

    Inflammatory cytokines, specifically TNF, IL-1, IL-6, as well as others, may play a causative role.

    Anorexia may be due to the effects of inflammatory cytokines on the hypothalamus with consequent

    changes in the balance of neurotransmitters stimulating or inhibiting food intake. Neuropeptide Y and

    Agouti Related Peptide (AGRP) are appetite-stimulating neurotransmitters; conversely the Opio-

    melanocortin and the Cocaine Amphetamine Related Factor (CART) neurotransmitter systems inhibit food

    intake.

    In health, leptin, which is produced in fatty tissue, inhibits appetite, while ghrelin,a hormone mainly produced

    in the stomach, stimulates appetite; both act through their influence on the neurotransmitter systems

    described above. These physiologic regulators seem overwhelmed in cachectic patients(loss weight); leptin

    levels are low and ghrelin levels are high, but all to no avail.

    4. Explain about horner syndrom / bernard syndrom ?

    Horner syndrome (Horners syndrome) results from an interruption of the sympathetic nerve supplyto the eye and is characterized by the classic triad of miosis (ie, constricted pupil), partialptosis,and

    loss of hemifacial sweating (ie, anhidrosis). The term Horner syndrome is commonly used in English-

    speaking countries, whereas the term Bernard-Horner syndrome is common in France.

    Causes of Horner syndrome include the following:

    Lesion of the primary neuron

    Brainstem stroke or tumor or syrinx of the preganglionic neuron In one study, 33%

    of patients with brainstem lesions demonstrated Horner syndrome[2]

    Trauma to the brachial plexus Tumors (eg,Pancoast)or infection of the lung apex

    Lesion of the postganglionic neuron

    Dissecting carotid aneurysmIn one study, 44% (65/146) of patients with internal

    extracranial carotid artery dissections had painful Horner syndrome, which remained

    isolated in half the cases (32/65)[3]

    Carotid artery ischemia

    Migraine

    Middle cranial fossa neoplasm

    5. Why he get pain in the lower chest and tightness when breathing ?

    6. Why the patient cough with blood ?

    Most of the lung's blood (95%) circulates through low-pressure pulmonary arteries and ends

    up in the pulmonary capillary bed, where gas is exchanged. About 5% of the blood supply

    circulates through high-pressure bronchial arteries, which originate at the aorta and supply

    major airways and supporting structures. In hemoptysis, the blood generally arises from

    this bronchial circulation, except when pulmonary arteries are damaged by trauma, byerosion of a granulomatous or calcified lymph node or tumor, or, rarely, by pulmonary

    arterial catheterization or when pulmonary capillaries are affected by inflammation.

    7. What are the relations between aktive smoker with the desease ?

    The pathogenesis of lung cancer is like other cancers, beginning with carcinogen-induced initiation events,

    followed by a long period of promotion and progression in a multistep process. Cigarette smoke both

    initiates and promotes carcinogenesis. The initiation event happens early on, as evidenced by similar genetic

    mutations between current and former smokers (e.g. 3p deletion, p53mutations).Smoking thus causes a

    field effect on the lung epithelium, providing a large population of initiated cells and increasing the chance of

    transformation. Continued smoke exposure allows additional mutations to accumulate due to promotion by

    chronic irritation and promoters in cigarette smoke(e.g. nicotine, phenol, formaldehyde). The time delay

    between smoking onset and cancer onset is typically long, requiring 20-25 years for cancer formation. Cancer

    risk decreases after smoking cessation, but existing initiated cells may progress if another carcinogen carries

    on the process.

    DIAGNOSIS

    pancoast tumor infiltration

    based on clinical manifestasi

    The most common initial symptomof Pancoast tumor is shoulder pain,

    which may radiate down to the armalong the ulnar nerve distribution.

    Pain occurs because of tumor infiltration

    of the brachial plexus,

    pleura, vertebrae, or upper three ribs

    Horner syndromea cluster ofsymptoms that include pupil constriction(miosis), drooping of the

    upper eyelid (ipsilateral ptosis),

    and an absence of sweating overthe affected side of the face (anhidrosis)

    occurs in up to half ofall patients with a Pancoast tumor.It results from involvement of the

    cervical paravertebral sympathetic

    General imaging differential considerations include

    pulmonary metastases

    mesothelioma

    primary chest wall tumours

    o Ewing sarcoma

    o PNET

    chest wall metastases

    apical pleural thickening secondary to previouspulmonary tuberculosis

    In addition a number of plain film mimics should be considered, including:

    ETIOLOGYThe vast majority of Pancoast tumors are lung cancersthough only 5% of lung cancers have this

    presentation.Non-small cell lung cancers are the most common etiology, and adenocarcinoma andsquamous cell carcinoma are the most frequent histologic types.Small-cell carcinomas are lesscommon since they usually develop centrally.Rare causes of Pancoast syndrome include other malignanttumors (primary or metastatic),hematologic processes,infectiousprocesses,and other nonmalignant

    conditions.Despite the rarity of these alternate etiologies, their possibility must be investigated prior to the initiationof therapy in order to achieve optimal outcomes. Thus, the clinical examination must be supplemented by

    imaging and histologic studies.
