https://t.me/medicina_free
437
Kaposiform Hemangioendothelioma (KH) andTufted Angiomas (TA)
• KH is benign vascular tumors appearing as violaceous cutaneous nodules that extend into deep tissues
• TA are more localized than KH and may not involve the skin
• Unlike infantile hemangioma, they do not spontaneously involute
• Have an endothelial and lymphatic component
• 42% present with Kasabach–Merrit phenomenon (see below)
• Treatment is with surgery ± chemotherapy
Kasabach–Merritt Phenomenon
• Severe thrombocytopenia that can occur in Kaposiform hemangioendothelioma or tufted angioma
• Treated with chemotherapy to decrease the risk of bleeding and may require transfusion to treat active bleeding
PHACES Syndrome
• Hemangioma associated with the following:
– Posterior fossa malformation – Hemangioma – Arterial abnormality and coarctation of the aorta – Cardiac defects – Eye abnormality – Sternal clefting
Symptoms
• Developmental delay, seizure, congenital stroke
Work Up
• Ophthalmology, cardiac, and neurologic investigation

Osler–Weber–Rendu Syndrome
• Aka Hereditary hemorrhagic telangiectasia (HHT)
• Autosomal dominant syndrome affecting blood vessels throughout body
Presentation
• Ectatic vessels of skin, mucous membranes, and viscera
• Epistaxis usually presenting symptom at puberty/early adulthood
• Skin telangiectasia can be punctate, linear, or spider like
• Mucous membranes of oral cavity, naso/oropharynx, and GI tract
• Associated with pulmonary, cerebral, and hepatic arteriovenous malformations
Diagnosis
• Hemorrhagic episodes (nasal cavity/nasopharynx, GI)
• Vascular ectasia
• Family history
Investigation
• Genetic testing available
• Must rule out cerebral and pulmonary AVM with imaging in children with fam­ily history
Treatment
• Supportive
• Electrocoagulation, photocoagulation (pulse-dye, Nd:YAG, argon beam)
– Bevacizumab (VEGF inhibitor) to reduce nosebleeds
Maffucci Syndrome
• Cavernous hemangiomas
• Chondrosarcoma (25% of cases)

439
• Dyschondroplasia
• Visceral vascular lesions
Sturge–Weber Syndrome (SWS)
• Capillary malformation involving eye, skin, and leptomeninges
• Nevus Flammeus (port wine stain) is a cutaneous facial venous dilation, hall­mark of SWS, and present at birth
• Seizure in up to 85% of patients, intellectual disability in 60%
• Requires ophthalmology and neurology workup

Cutaneous andTemporal Bone Malignancies
KevinWong, HailunWang, BrettA.Miles, andMohemmedKhan
Pearls
• The most signicant risk factor to cutaneous malignancy is ultraviolet (UV)
radiation
• UVB light (200–320nm) more carcinogenic than UVA light (320–400nm)
• Basal cell carcinoma (BCC) most common cutaneous malignancy
• For melanoma, tumor depth is the most important prognostic factor for stage 1
and 2 disease; however, lymph node involvement is the most important factor for stage 3 disease
• Squamous cell carcinoma (SCC) accounts for 70% of all tumors in the ear canal,
middle ear, and mastoid cavity
• Lateral temporal bone resection with or without auriculectomy, craniotomy,
mandibulectomy, neck dissection, or parotidectomy may be needed for advanced temporal bone malignancies

malignancies
• High-dose interferon-a 2b is the only FDA-approved adjuvant therapy for stage
III melanoma

Anatomy
• Layers of skin (supercial to deep)
– Epidermis
Stratum corneum Stratum granulosum Stratum spinosum Stratum germinativum/basale
– Dermis
Papillary dermis Reticular dermis
– Melanocytes=melanin-producing cells located in stratum basale; responsible
for skin pigmentation
– Basal cells=small, round, epithelial cells found in stratum basale
• Temporal bone
– Four parts: squamous, mastoid, petrous, and tympanic – Middle ear (points of spread)
Anterior: Eustachian tube Medial: round window, oval window Posterior: mastoid cavity Superior: tegmen tympani
– External auditory canal (EAC)
Lateral 1/3: cartilaginous, cerumen glands (modied sebaceous glands) Medial 2/3: bony, epithelium is adherent to periosteum, resistant to radial spread of cancer Huschke foramen: developmental defect in tympanic ring → anterior extension of EAC malignancy to parotid Fissures of Santorini: small dehiscences in anterior cartilage → direct radial EAC tumor extension
• Lymphatic drainage
– Auricle and EAC: periparotid lymph nodes (LN), parotid gland, jugular chain,
LN overlying mastoid
– Medial EAC, middle ear: retropharyngeal nodes, deep jugular nodes

Basal Cell Carcinoma
Epidemiology
• Most common skin cancer (65%)
• Worldwide incidence increasing
• Locally destructive but least likely to metastasize (risk 0.1%)
• Average age at diagnosis=64.4years old
Presentation
• Slowly enlarging “pearly” skin lesion, ulceration, papule/nodule within scar
• Local tissue destruction
• Fair skin (Fitzpatrick scale type 1) has 10–20× higher risk
Etiology/Pathogenesis
• Ultraviolet radiation
443
– Sunlight, tanning booths, UV light therapy
Latency period 20–50years
– UV radiationmodify nucleic acids → activation of oncogenes or inactiva-
tion of tumor suppressor genes
– Other radiation=X-ray, Grenz-ray
• Gene mutations
– TP53 (tumor protein p53) – Patched (PTCH)=tumor suppressor gene, Gorlin syndrome – Patched homologue 1 (PTCH1) = loss-of-function mutation, sporadic and
familial cases of BCC
– Sonic hedgehog (SHH), smoothened (SMO), Gli = gain-of-function muta-
tions, sporadic and familial cases of BCC
• Immunosuppression
– 10× higher incidence of skin cancer in transplant patients
• Other causes:
– Arsenic ingestion (Fowler solution, water contaminant) – Trauma
444
https://t.me/medicina_free
– Xeroderma pigmentosum
Autosomal recessive Photosensitive skin with multiple BCCs and other cutaneous malignancies
– Epidermodysplasia verruciformis (Treeman syndrome)
Autosomal recessive Vulnerability to human papillomavirus leading to multiple scaly macules and increased susceptibility to BCC, SCC, and warts
– Nevoid basal cell carcinoma syndrome (Gorlin syndrome)
Autosomal dominant Defect in PTCH 1 tumor suppressor gene on chromosome 9 leading to multiple BCCs, odontogenic keratocysts, hyperkeratosis of palms and soles, intracranial calcications, brain tumors, and rib anomalies
– Bazex syndrome (paraneoplastic acrokeratosis)
Rare paraneoplastic syndrome characterized by follicular atrophoderma, BCCs, and local anhidrosis
– Rombo syndrome
Autosomal dominant Multiple BCC, trichoepithelioma, hypotrichosis, cyanosis of the hands and feet
K. Wong et al.
– Alcohol consumption
Positive association between excessive alcohol use and incidence of sunburns
Diagnosis
• Shave or punch biopsy
• Dermatoscopy: arborizing telangiectasia, blue-grey globules, blue-grey ovoid
nests, spoke wheel areas
• Histopathology
– Undifferentiated (solid type): basaloid cell proliferation with extension into
papillary dermis, palisading peripheral columnar cells
– Differentiated: keratotic (hairlike structures), cystic (sebaceous, gland-like
structures), adenoid (tubular structures, lacelike pattern)

• High-risk features:
– Tumor >2mm thickness or Clark levelIV (see Breslow and Clark below) – Perineural invasion (PNI) – High-risk anatomic area: lip (vermilion and hair-bearing), ears, temple, pre-
and postauricular region, central face, eyelids, nose, lips, chin, mandible – Poorly differentiated or undifferentiated histology – Recurrence
• Types (multiple)
– Nodular: low risk, most common, pearly/translucent, rolled edges, telangiec-
tasia, central depression, ± ulceration – Supercial: low risk, scaly, pink, patch or plaque, more common on trunk/
extremities – Morpheaform: high risk, at or depressed, whitish scar; aggressive, worst
prognosis – Pigmented: similar to nodular type, more pigmented, resembles melanoma or
benign nevus – Fibroepithelioma: raised, rm, pedunculated or sessile, red with smooth surface – High risk: basosquamous, micronodular, mixed inltrative, sclerosing

Treatment Recommendations
• Overview
– Prognosis excellent, survival approaches 100% if no spread to other sites – Metastasis rare; common sites=lymph nodes, lungs, bones – 5-year risk of new primary=50% – 5-year recurrence=5% (depending on treatment modality)
• Surgical excision
– Gold standard – 4- to 5-mm margins for low-risk disease (<20mm) – 5- to 10-mm margins for high-risk disease (>20mm)
447
Morphoeic: 82% cleared with 5 mm margins, >95% cleared with 13–15mm margins
• Mohs micrographic surgery (MMS)
– Indicated for cosmetically sensitive and high-risk disease (size >2cm, ill-
dened borders, recurrence, PNI, or high-risk anatomic sites such as central face, eyes, nose, lips, ears)
• Radiotherapy (RT)
– Higher recurrence rate than surgery, less acceptable cosmetic outcomes – Primary radiation for nonresectable disease – Adjuvant radiation indicated for positive margins and PNI
• Photodynamic therapy
– Methyl aminolevulinatecancer cell uptakeprotoporphyrin IX→visible
red lightgenerate free radicals and oxygen speciescytotoxic
– Better cosmesis but higher recurrence rate compared to surgery
• Curettage and cautery
– Indicated for low-risk disease – High recurrence rate; not as commonly used – Consider in small nodular or supercial lesions – Poor outcomes for high-risk lesions
