microcystic adenocarcinoma
Introduction
Introduction to microcystular adenocarcinoma Microcysticadenexacarcinoma (microcysticadenexacarcinoma), also known as sclerosingsweatductcarcinoma, is similar to sclerosing tumor, immunohistochemical study, tubular structure CEA positive, tumor cell cord, horn cyst and tubular structure keratin staining are positive , suggesting that it differentiates into hair and small sweat glands. Tumors usually show very slow-growing skin or pale yellow plaques or nodules. It occurs in the face, especially the upper lip, but it can also occur in other parts such as the armpit. Age is not limited, there is no difference between men and women. basic knowledge The proportion of illness: 0.0025% Susceptible people: no special people Mode of infection: non-infectious Complications: sarcoidosis
Cause
Microcystic adenocarcinoma
(1) The cause of the disease is still unknown. Tumors usually show very slow-growing skin or pale yellow plaques or nodules. It occurs in the face, especially the upper lip, but it can also occur in other parts such as the armpit. Age is not limited, there is no difference between men and women. About 50% of patients may have local recurrence, local invasion of neuromuscular bones, etc., and no metastasis has been found.
(2) The pathogenesis of pathogenesis is still unclear. According to clinical manifestations, the characteristics of skin lesions, histopathology, and immunohistochemistry can be diagnosed.
Prevention
Microcyst adenocarcinoma prevention
There are no effective preventive measures for this disease. Pay attention to health, do a good job of safety protection, reduce and avoid the irritating and accidental injury of adverse factors, can play a certain preventive role; In addition, early detection, early diagnosis and early treatment are also the key to prevention and treatment of this disease. In case of onset, active treatment should be actively treated to prevent complications.
Complication

Symptom
Microcystic gland cancer symptoms Common symptoms Nodular sclerosis cyst
Tumors usually show very slow-growing skin or yellowish plaques or nodules, which occur in the face, especially in the upper lip, but can also occur in other areas such as the armpits. Age is not limited. There is no difference between men and women. About 50% of patients can be localized. Recurrence can locally invade the neuromuscular bones, etc., and no metastasis has been found.
According to clinical manifestations, the characteristics of skin lesions, histopathology, and immunohistochemistry can be diagnosed.
Examine
Examination of microcystic adenocarcinoma
Histopathology: The tumor is located in the dermis and even in the subcutaneous tissue. Most of the squamous cells form nests or cord-like masses embedded in the mesenchymal interstitial of the collagen. In some clumps, keratinous cysts or a small amount of transparency can be seen. Keratinous granules, some squamous cell nests or cords can be seen in tubular structures similar to sphincter tumors, varying in number, lining up single-layer or double-layered cuboid cells, cells can be atypical, with a few mitotic figures.
Immunohistochemical study, tubular structure CEA positive, tumor cell cord, horn cyst and tubular structure keratin staining were positive, suggesting that it differentiated into hair and small sweat glands.
Diagnosis
Diagnosis and differentiation of microcyst adenocarcinoma
According to clinical manifestations, the characteristics of skin lesions, histopathology, and immunohistochemistry can be diagnosed.
The tumor is located in the dermis, even in the subcutaneous tissue, and is nested or cord-like in many squamous cells, embedded in the mesenchymal interstitial of collagen. Keratinous cysts or small amounts of clear keratinous granules can be seen in certain masses. Some squamous cell nests or cords can be seen in tubular structures resembling sphincter tumors, varying in number, lining up single or double cuboid cells. Cells can be atypical, with a few mitotic figures.
