This document discusses lymphadenopathy (lymphadenitis), which is the inflammation or enlargement of lymph nodes. Lymph nodes can enlarge due to infection or infiltration by neoplastic cells. Enlargement of peripheral nodes causes visible and palpable swellings, while enlargement of internal nodes may cause obstruction of the esophagus, pharynx, trachea or bronchi. Common causes of lymphadenopathy in various animals include infections by bacteria such as Corynebacterium pseudotuberculosis in sheep and cattle. Clinical signs may include pain and swelling in lymph nodes, as well as secondary signs from obstructions. Diagnosis involves history, clinical signs, biopsy and culture. Treatment focuses on addressing the underlying

cutaneous tuberculosis
Cutaneous tuberculosis can present in several forms based on the route of infection and immune status of the host. Lupus vulgaris is the most common form in adults, presenting as slowly expanding reddish plaques on the head and neck. Scrofuloderma results from contiguous spread from underlying bone or lymph node infection, causing ulcerating nodules. Tuberculosis verrucosa cutis, or warty tuberculosis, occurs through inoculation and presents as painless verrucous plaques. Diagnosis involves biopsy showing granulomatous inflammation with caseation necrosis and occasionally visualizing acid-fast bacilli. Treatment involves anti-tubercular therapy targeting Mycobacterium tuberculosis.
lymphangitis.ppt
This document discusses lymphangitis and lymphadenitis. Lymphangitis is defined as inflammation of the lymphatic channels that occurs as a result of infection at a site distal to the channel. Common causes include streptococcal bacteria. Symptoms include red streaks on the skin extending from the infection site toward lymph nodes. Treatment involves antibiotics. Lymphadenitis is inflammation of lymph nodes, which can be caused by various bacteria, viruses, fungi or other pathogens. Evaluation may involve imaging and biopsy to determine the cause and guide treatment.
Skin systemic infections final
Cutaneous manifestations of systemic infections can include:
1. Osler nodes and Janeway lesions in infective endocarditis, appearing as tender nodules on fingers or palms.
2. Rashes caused by viral exanthems like measles, rubella, enteroviruses. Measles causes Koplik's spots.
3. Fungal infections in immunocompromised patients like candidiasis, dermatophytosis, cryptococcus causing papules or plaques.
4. Bacterial infections may cause cellulitis, ecthyma gangrenosum from Pseudomonas, or disseminated lesions in meningococcemia.
Skin infections (3).pdf
This document summarizes various surgical infections of the skin and subcutaneous tissues. It describes cellulitis as spreading inflammation of subcutaneous tissues, often caused by Streptococcus pyogenes or gram-negative bacteria. Erysipelas is a similar condition caused by S. pyogenes that presents with a rose pink rash and lymphangitis. Abscesses form when infections become localized and contain pus within a cavity lined by granulation tissue. Management of these conditions involves antibiotics, drainage of pus, and dressing wounds. More severe infections like gas gangrene are caused by Clostridium bacteria and cause necrosis of muscle tissue and production of gas within tissues.
Lymphangitis-1.pptx physiotherapy ppt general surgery
Lymphangitis is an inflammation of the lymphatic vessels, most often caused by bacterial infections like streptococci and staphylococci entering through the skin via wounds or insect bites. Filariasis, caused by parasitic worms transmitted by mosquitoes, is a common cause in certain regions. Symptoms include fever, skin redness along the path of the lymphatic vessels, and swollen lymph nodes near the infection site. Treatment involves antibiotics, pain medication, limb elevation, and physiotherapy to promote lymph drainage and prevent lymphedema.
ACUTE INFECTION [Autosaved].pptx
This document summarizes various acute bacterial infections including cellulitis, Ludwig's angina, lymphangitis, abscesses, and tuberculous lymphadenitis. Cellulitis is a spreading skin infection caused by streptococci that leads to inflammation. Ludwig's angina involves cellulitis of the neck region accompanied by mouth swelling. Lymphangitis presents as red streaks along lymphatic vessels. Abscesses are localized pus collections that can be pyogenic, pyemic, or cold. Tuberculous lymphadenitis commonly affects cervical lymph nodes and progresses through stages of lymphadenitis, matting, cold abscess, and sinus formation. Other infections discussed include boils, carbuncles

Prurigo.pdf
Prurigo is a group of skin diseases characterized by intensely itchy papules or nodules without an identifiable local cause. It is caused by severe chronic itching leading to repetitive scratching and skin irritation. This results in a lymphocyte-rich inflammatory infiltrate, activated keratinocytes and sensory nerves, and increased collagen tissue. Clinically, prurigo nodularis appears as sharply demarcated, tough nodules on the extensor surfaces that the patient scratches, causing excoriations and ulcerations. Treatment involves eliminating pruritus through antipruritic medications, corticosteroids, calcineurin inhibitors, phototherapy, or systemic therapies. Cryosurgery can also be used

LYMPHANGITIS and lymphoedema.pptx
Lymphangitis is an inflammation of the lymphatic channels caused by bacterial infections like streptococci and staphylococcus. Risk factors include diabetes, immunodeficiency, and steroid use. Microorganisms enter through broken skin and travel along lymphatic vessels, causing red streaks. Symptoms are tender red lines spreading from the infection site towards lymph nodes, with fever and aches. Diagnosis is clinical but may include blood tests and imaging. Treatment involves antibiotics, rest, elevation, and incision/drainage of abscesses. Prognosis is good with proper antibiotics but morbidity relates to underlying infection.
Lymphedema is fluid accumulation caused by lymphatic system failure. It can
Cold abscess
1) Cold abscesses are collections of pus that develop slowly without signs of inflammation and are usually caused by tuberculosis infection elsewhere in the body, commonly the lymph nodes or bones.
2) They form via a pathological process where the tuberculosis bacteria are phagocytosed by immune cells, forming granulomas with caseous necrosis that can break down and track along tissue planes, appearing as painless swellings distant from the original infection site.
3) Diagnosis involves tuberculin skin testing, biopsy or aspiration of the abscess, and radiological imaging like ultrasound or CT scan may help locate the abscess. Treatment consists of anti-tuberculosis drugs alongside drainage of palpable abscesses.
