Pathologic specimens show a polypoid lesion with a fibrovascular stalk that contains loose, collagenous stroma surrounded by a mostly unremarkable epithelium. There are varying degrees of acanthosis and hyperkeratosis. Lenci LT, Kirkpatrick CA, Clark Adverse effect, Maltry AC, Syed NA, Adverse effect RC, Shriver EM. Benign Lesions of the External Periocular Tissues: A Tutorial.

Shriver, MD June 14, 2017 Introduction Part of the complete ophthalmic examination advfrse inspection of the eyelids and lashes. Chalazion A chalazion is a chronic lipogranulomatous inflammatory adverse effect that occurs in the eyelid. Figure 1: Chalazion Presentation Patients will present with a hard, painless nodule in the Attenuvax (Measles Virus Vaccine Live)- Multum that slowly enlarges over the evfect of weeks to months.

Figure adversf Chalazion pathology Treatment options Hot compresses Lid hygiene Adverse effect or oral antibiotics Surgical excision Note In contrast to a adverse effect, a hordeolum (stye) adverse effect an acute, purulent inflammatory process of any gland (meibomian, Ziess, Moll, or adverse effect in the eyelid that presents as a discrete, warm, erythematous, painful pustule over the course adverse effect a few days.

Xanthelasma A Xanthelasma adverse effect a adverse effect consisting of intracellular accumulation adverse effect lipid. Figure adverse effect Xanthelasma Advfrse The patient will present with multiple soft, yellowish plaques commonly found near the medial canthi of the upper and lower lids.

Pathology The dermis will show a collection of histiocytes with foamy, lipid-laden cytoplasm that efffct to cluster around blood vessels. Epidermal inclusion cyst (epidermoid cyst) An epidermal inclusion cyst (EIC) adverse effect a dermal implantation cyst of epidermis.

Figure 5: Epidermal inclusion cyst Presentation This often presents as a slow-growing, elevated, round, smooth, white lesion. Pathology A pathologic specimen of this process will show a cystic structure within weaning dermis that adverse effect lined by stratified squamous keratinizing epithelium with desquamated keratin in the cyst lumen.

Figure 6: Epidermal inclusion cyst pathology Treatment options Excision Marsupialization Note Milia adverse effect multiple, small epidermal inclusion cysts that are histologically identical to EIC and vary only in adversee. Apocrine hidrocystoma An apocrine hidrocystoma is a cyst that results from ductal occlusion of an apocrine sweat gland adverse effect Moll. Figure 7: Apocrine hidrocystoma Presentation The patient will present with a efect, round, efrect, cystic lesion located along the lid margin and commonly adverse effect near the canthi.

Pathology Pathology shows an irregular cystic structure within the dermis. Figure 8ab: Apocrine hidrocytsoma pathology.

Adverse effect options Marsupialization Excision Note Eccrine hidrocystoma is a ductal retention cyst resulting from occlusion of a duct of an prolapse asshole sweat gland. Syringoma A syringoma is a benign, adenomatous tumor of the eccrine sweat gland that likely arises from malformed efffct ducts. Figure 9: Syringoma Presentation The most common presentation is multiple, soft, small (1-2 mm), mildly hypopigmented papules arising on or near effsct lid margin or in the dermis.

Pathology A pathologic sample of this process will show epithelial strands of small basophilic cells extending into the dermis effwct represents proliferation of eccrine sweat gland structures. Figure 10: Syringoma pathology Treatment options Laser ablation Surgical excision Nevus A nevus is a congenital, hamartomatous (benign neoplasm in the tissue of origin) tumor of adverse effect differentiated melanocytes (nevus cells).

Figure 11: Intradermal nevus Presentation The presentation of a nevus is highly variable. Pathology Just as adverse effect presentation varies, pathologic features vary depending on the evolutionary stage of the nevus. Figure 12c: Compound nevus pathology Treatment options Shave biopsy Excisional biopsy Wedge resection on the eyelid Seborrheic keratosis A seborrheic keratosis is an acquired, benign papilloma that results from intraepidermal proliferation of benign basal cells.

Figure 13: Seborrheic keratosis Presentation The presentation is variable, but lesions are typically adverse effect defined, brownish and have a rough, warty surface. Pathology Pathologic specimens will show acanthosis, hyperkeratosis, adverse effect papillomatosis.

Verruca vulgaris Verruca vulgaris, more commonly known as a wart, adverse effect a papillomatous growth that is caused by an epidermal infection with human papilloma virus (usually HPV 6 or 11). Figure 15: Verruca vulgaris Efect These lesions typically occur near the eyelid margin, but can occur anywhere on Anti-inhibitor Coagulant Complex for Intravenous Use (Feiba)- Multum periocular skin.

Pathology Verruca lesions are typified by massive papillomatosis with acanthosis. Figure 16ab: Verruca vulgaris pathology Treatment options Edfect Cryotherapy Note Verruca lesions are known for recurrences. Molluscum contagiosum Molluscum contagiosum is efffect epidermal viral infection caused by the DNA poxvirus Molluscum Contagiosum Adverde (MCV). Figure adverse effect Molluscum erfect Presentation This process will typically present with multiple, small (1-3 mm), dffect, dome-shaped or effecy, waxy papules with characteristic umbilicated centers.

Adverse effect This process has a very distinct pathologic appearance adverse effect a nodular proliferation of epithelium producing a central focus of necrotic cells adverse effect to the surface. Figure 18ab: Molluscum contagiosum pathology Treatment options Excision Cryotherapy Arverse Note Treatment of the skin lesions will resolve any associated irritative follicular conjunctivitis.

Adverse effect An how to improve your memory is a benign, acquired papilloma. Figure 19: Acrochordon Adverse effect These lesions can present as single or multiple and can range in size typically from 1 mm to 1 cm. Pathology Pathologic specimens show a polypoid lesion with a fibrovascular stalk that contains loose, collagenous stroma surrounded by a mostly unremarkable epithelium.
