Lentigo Maligna and Lentigo Maligna Melanoma

Please tweet and retweet Tweet

Lentigo maligna is a melanoma in situ that forms in sun exposed areas of skin, first described in 1892. Under the microscopic one sees a proliferation of atypical pigment cells in the superficial skin. They typically have a cloud like appearance with variable shades of brown coloring and start as a freckle that enlarges over a number of years. Historically they were called Hutchinson's freckle. More than half occur on the face or neck. They are more common in warmer climates with greater sunlight exposure and the majority occur after the 6th decade of life . If ignored long enough they will develop a vertical growth phase and begin to invade the deeper layers of skin, dermis. They are then malignant melanomas and are called lentigo maligna melanoma. At the time of presentation 10 to 20% of lentigo malignas have already invaded the dermis to some degree. Although melanoma represents a small portion of all skin cancers, it is responsible for the majority of skin cancer–related deaths.

The diagnosis of melanoma of the lentigo maligna subtype is challenging, as the clinical presentation is quite varied, ranging from a subtle brown patch to tan/black or even amelanotic(almost normal skin color). These lesions pose significant treatment challenges for clinicians because of significant invisible to the eye surrounding extension, a predilection for cosmetically and functionally sensitive areas, and a naming system that is often confusing. Obtaining a biopsy specimen from a clinically suspicious lesion can present problems, given the lesions can be as large as 6cm in anatomically and cosmetically sensitive areas. If the suspicious lesion is small, an excisional biopsy of the entire pigmented lesion to fat is recommended. However, an excisional biopsy is rarely feasible, as most lesions are too large with poorly defined margins to be completely removed. In this setting, a small biopsy of the darkest, or most palpable, or otherwise most visibly concerning area of the lesion is recommended.

Intra-Uterine Device (IUD) Birth Control and Plastic Surgery

An intrauterine device is a small contraceptive device, often 'T'-shaped, often containing either copper or levonorgestrel, which is inserted into the uterus. They have a 0.2% to 0.8% typical use failure rate, compared to an 18% failure rate for condoms and 9% failure rate for the pill. Hormonal IUDs can last around three to six years depending on the brand, and the non-hormonal IUD can last up to 12 years.

Breast Implants and Breastfeeding

Breastfeeding is a vital function for infant mother bonding, transmission of antibodies to the baby to fight infection etc. All women with breast implants and no other prior breast surgery giving birth at an Argentinian hospital between April 2013 and July 2014 were followed and compared to body matched mothers and babies. After giving birth those with breast implants had insignificantly lower success at breastfeeding at 30 days after giving birth than those women who did not have breast implants: 93% with implants vs. 97% without implants. Also, it did not matter whether the implants were placed via incisions in the crease under the breast or in the outer edge of the areola (skin around the nipple). Therefore we can conclude that most women can establish breastfeeding even if they have breast implants irrespective of how the implants were placed.

PicoWay tattoo removal laser (Syneron Candela) surveyed 250 people who had one or more tattoos removed and 100 people who were thinking about removing one or more of their tattoos between 9/29/2016 and 10/6/2016. 83% who had a tattoo removed were planning on getting a new tattoo and were more likely to do so because they know they have the option of removing it. 13% of this group had it removed because they had become parents. The most commonly removed tattoos were a person’s name. Symbols and animals came in a close second and third.

The person who removed the tattos was:

Angioedema and Cosmetic Surgery

Please tweet and retweet Tweet

Angioedema is rapid swelling (edema) of the dermis (deep skin), subcutaneous tissue (fat), mucosa and submucosal tissues (gastrointestinal or other hollow organ lining) that was first described in 1882. It is characterized by repetitive episodes of asymmetric swelling, frequently of the face, lips, tongue, limbs/hands or feet, and genitals that lasts 24 to 60 hours without itching or hives. In the gastrointestinal lining it can cause severe pain and increased girth with or without diarrhea or vomiting leading to unnecessary abdominal or gynecologic surgery. In the respiratory tract including the mouth and throat it can interfere with speech or swallowing and cause life threatening asphyxiation. In the urinary tract it can prevent urination. In the hands or feet it can preclude the use of the hands or ability to walk. In the face the eyes can be swollen shut.

Its prevalence is 1 in 10,000 to 1 in 50,000 individuals. It is classified as:

Acquired (swelling occurs over a few minutes)	Hereditary(HAE)-genetic mutation and usually manifests in the second decade of life (swelling occurs over 2 to 8 hours)
immunologic-IgE antibody mediated allergies to foods, drugs or particles in the air like pollen, autoimmune and caused by the body's release of histamine or antibodies against the C1-esterase inhibitor protein	type I-decreased levels of C1-esterase inhibitor protein in the blood, 85% of hereditary type
nonimmunologic- side effect to certain medications, particularly Angiotensin Converting Enzyme inhibitors, NSAIDs like motrin, advil or aspirin, birth control pills containing estrogen, food additives that cause increased bradykinin levels	type II-dysfunctional C1-esterase inhibitor protein in the blood, 15% of hereditary type
idiopathic-unknown cause	type III-abnormal factor XII in blood clotting cascade so it is more active
cancer such as carcinoid or blood cancers

HAE attacks are caused by the production of large amounts of bradykinin, that is normally broken down by C1-esterase inhibitor protein, in the bloodstream.

In the absence of C1-esterase inhibitor protein activity (the yellow dots) bradykinin production continues uncontrolled. These patients are deficient in C1-esterase inhibitor protein so the metabolic pathway depicted in the above diagram goes into overdrive. FXII is factor XII a component of the blood clotting cascade. Bradykinin increases blood vessel diameter and pore size with leaking resulting in swelling of the tissue through which the blood vessels travel. It is so powerful that 1 microgram injected into the brachial artery increases arm blood flow 6 fold. Dental treatment, particularly tooth extraction, is a recognized trigger of HAE though symptoms may not manifest for many hours or even days after the procedure. A typical course resolves in 5 to 7 days, but in some patients, the clinical manifestations exist up to 6 weeks. Other known triggers are physical/psychological stress, fatigue, menstrual periods, pregnancy, trauma and having a breathing tube placed for anesthesia. 75% of patients with HAE have a relative who suffers from repetitive bouts of swelling. The remaining 25% are spontaneous without an affected relative. The diagnosis can be made by blood tests measuring the blood complement cascade proteins C1 and C4. Unlike allergic edema, HAE attacks do not respond to antihistamines, steroids or adrenaline including Epipens. The attacks vary in frequency, type and severity which contributes to delays in seeking treatment. 50% of HAE patients will have a laryngeal (voice box) attack within their lifetime, 40% of which are fatal if not treated emergently.
