Definition and general information of Seborrheic keratosis

Synonyms: basal cell papilloma, seborrheic wart, senile wart

Seborrheic keratosis ICD 10 code L82 is a benign skin tumor in old and senile age, single or multiple, hyperpigmented spot, plaque or knot with a smooth, scaly, or verrucous surface, with the pronounced hyperkeratosis. It is characterized by the proliferation of spiny and basaloid cells with the formation of horny cysts.

Etiology and pathogenesis of Seborrheic keratosis

In the keratotic type (the most common), significant hyperkeratosis, acanthosis, and papillomatosis are found. The stratum corneum invaginates in places into the epidermis, resulting in the formation of cystic cavities filled with stratum corneum (pseudo-horny cysts). The acantotic variant is characterized by a sharp thickening of the epidermis, while hyperkeratosis and papillomatosis are insignificant. There are a large number of pseudo-horny cysts. The adenoid type is characterized by numerous thin stripes consisting of two rows of cells that resemble basal cell epithelioma cells. The stripes branch and intertwine and usually contain significant amounts of melanin. There are no cystic inclusions of horny masses.

Seborrheic keratosis ICD 10 Clinical manifestations

Clearly delimited spotty, plaque-like, or nodular elements from 2-3 mm to 1 cm or more, varying degrees of pigmentation, with a warty surface containing horny plugs, often covered with dry keratotic masses. It usually occurs in people over 50 years old, localized in any areas of the skin, but mainly on the skin of the trunk. Growth is slow. A sudden disseminated spread of seborrheic keratomas may be a paraneoplastic sign ( Leser-Trelatt syndrome ).

Differential diagnosis

Differential diagnosis of Seborrheic Keratosis ICD 10, code L82 is carried out with actinic keratosis (flat, rough on palpation, small elements of skin color), eccrine pore (more often single elements on the palms and soles), melanoma (uneven polychromatic color and borders).

Seborrheic Keratosis: Treatment

Electrocoagulation, cryodestruction, laser coagulation. With massive keratotic layers, it is advisable to pre-apply 1% salicylic acid ointment for 3-5 days.
