Skin & Skin Infections
The skin has three main layers - the epidermis, dermis and hypodermis. The epidermis is the outer protective layer, the dermis is a lower supporting layer that gives strength and acts as a reservoir to fight infections, and the hypodermis is a layer of fatty tissue that supports the skin. The skin acts as a protective barrier and plays roles in temperature regulation, sensation, and waste excretion. Fungal infections can be superficial or deep, with superficial infections affecting the outer layers and deep infections invading living tissue. Corticosteroids are anti-inflammatory drugs that work by suppressing the immune system and inflammatory response.

#Skin malignancy is the most common malignancy in fair-skinned populations.
#Skin malignancies are either non-melanoma or melanoma.
#A persistent skin lesion that does not heal is highly suspicious for malignancy and should be examined by a health care provider.
# Early detection and treatment can often lead to a highly favourable prognosis.
Skin tumors
Skin tumors can be benign or malignant. Benign tumors include seborrheic keratosis, skin tags, epidermoid cysts, and milia. Malignant tumors include basal cell carcinoma, squamous cell carcinoma, and malignant melanoma. Basal cell carcinoma is the most common skin cancer, usually appearing as a painless raised area on sun-exposed skin. Squamous cell carcinoma can also develop from sun exposure and occasionally spread. Malignant melanoma is more likely to metastasize and its risk factors include fair skin, many moles, and intense sun exposure. Proper diagnosis and treatment of skin tumors is important for patient prognosis and outcomes.
Skin cancer
This document summarizes different types of skin cancer and their characteristics. It discusses the three main types: non-melanoma skin cancers like basal cell carcinoma and squamous cell carcinoma, and melanoma. Basal cell carcinoma is the most common type, usually appearing as nodular lesions on sun-exposed areas. Squamous cell carcinoma is also common and can metastasize. Melanoma subtypes include superficial spreading, nodular, lentigo maligna, and acral lentiginous. Prevention strategies focus on reducing sun exposure and applying sunscreen. Surgical excision is a common treatment, along with Mohs surgery, radiation, and medical therapies.
Skin tumors
Skin tumors can be benign or malignant. Seborrhoeic keratosis is a common benign epidermal tumor unrelated to sebaceous glands that usually arises after age 50 as multiple 'stuck-on' lesions on the face and trunk. Malignant skin tumors include basal cell carcinoma, the most common type of skin cancer, squamous cell carcinoma, and malignant melanoma. Risk factors for these cancers include sun exposure. Accurate diagnosis and treatment is important given the risk of local invasion and metastasis for malignant skin tumors.

pathology of skin malignancy
This document summarizes various types of skin malignancies:
- It classifies skin tumors into keratinocytic (basal cell carcinoma, squamous cell carcinoma), melanocytic (malignant melanoma), and appendageal tumors.
- It describes the histological features and pathogenesis of common tumors like basal cell carcinoma, squamous cell carcinoma, and malignant melanoma. It notes their association with mutations in signaling pathways like Hedgehog and TP53.
- It also summarizes less common tumors like pilomatric carcinoma, sebaceous carcinoma, mycosis fungoides, and dermatofibrosarcoma protuberans, noting their clinical features, histology, and prognosis
Skin cancers
Skin cancer is the most commonly diagnosed cancer. The three main types are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and malignant melanoma. BCC is the most common type and usually appears as a waxy nodule, while SCC can metastasize if not treated early. Malignant melanoma is the most lethal type and risk factors include ultraviolet light exposure and family history. Early detection of skin lesions is important, and treatment may involve surgical excision, Mohs surgery, radiation, or chemotherapy depending on the cancer type and stage. Education about skin cancer signs and protecting skin from the sun are also important.

2. Benign eyelid tumours include papillomas, naevi, haemangiomas, xanthelasma, keratoacanthomas, neurofibromas, and sebaceous adenomas. Premalignant tumours include actinic keratosis and xeroderma pigmentosa.
3. Malignant eyelid tumours consist of squamous cell carcinoma, basal cell carcinoma, malignant melanoma, and sebaceous gland carcinoma. Orbital tumours can be primary, secondary, or metastatic and include developmental tumours,
Malignant skin diseases
This document provides information about malignant skin diseases and ulcers. It discusses skin cancer epidemiology and risk factors. The main types of skin cancer covered are malignant melanoma and basal cell carcinoma. Malignant melanoma types include superficial spreading melanoma, nodular melanoma, lentigo maligna melanoma, and acral lentiginous melanoma. Survival rates are related to melanoma thickness. Treatment options for skin cancers include surgery, adjuvant therapy, isolated limb perfusion, and intra-arterial chemotherapy. Common ulcers seen in practice include venous, ischemic, diabetic/neuropathic, and neoplastic ulcers.

Eyelid inflammation & tumors
The document discusses various eyelid conditions including inflammation, tumors, and cysts. It describes blepharitis as inflammation of the eyelid margin that causes redness, grittiness, and burning. It distinguishes between anterior and posterior blepharitis. Common benign eyelid lesions include chalazia (meibomian cysts), styes (hordeola), molluscum contagiosum, xanthelasma, and sebaceous cysts. Malignant eyelid tumors discussed are basal cell carcinoma, squamous cell carcinoma, and melanoma. Treatment options involve lid hygiene, warm compresses, antibiotics, and surgical excision or cryotherapy depending on the condition.
Ocular and Orbital Tumours.pptx
This document discusses various ocular and orbital tumours. It begins by providing an overview of orbital anatomy and the effects of space-occupying lesions. It then discusses the most common paediatric and adult orbital tumours. Specific tumour types are examined in more detail, including retinoblastoma, rhabdomyosarcoma, lacrimal gland tumours, squamous cell carcinoma, and orbital metastases. For each tumour, the document outlines epidemiology, clinical presentation, investigations, differential diagnosis, and treatment approaches.
Malignancies 2013
The document reviews ocular malignancies of the eyelids, cornea, conjunctiva, and iris. It discusses the most common eyelid tumors including basal cell carcinomas, squamous cell carcinomas, sebaceous cell carcinomas, and melanomas.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Artificial Intelligence Symposium (THAIS)
