Hidradenoma refers to a benign adnexal tumor of the apical sweat gland. These are 1–3 cm translucent blue cystic nodules. It usually presents as a single, small skin-colored lesion, and is considered distinct from the closely related poroma. Hidradenomas are often sub-classified based on subtle histologic differences, for example:
Hidrocystoma is an adenoma of the sweat glands.
Schöpf–Schulz–Passarge syndrome is an autosomal recessive condition with punctate symmetric palmoplantar keratoderma, with the keratoderma and fragility of the nails beginning around age 12. In addition to palmoplantar keratoderma, other symptoms include hypodontia, hypotrichosis, nail dystrophies, and eyelid cysts. Patients may also develop syringofibroadenoma and squamous cell carcinomas.
Desmoplastic melanoma is a rare cutaneous condition characterized by a deeply infiltrating type of melanoma with an abundance of fibrous matrix. It usually occurs in the head and neck region of older people with sun-damaged skin. Diagnosis can be difficult as it has a similar appearance to sclerosing melanocytic nevi as well as some nonmelanocytic skin lesions such as scars, fibromas, or cysts.
Spiradenoma, also spiroma or eccrine spiradenoma, is a cutaneous condition that is typically characterized, clinically, as a solitary, deep-seated dermal nodule of approximately one centimeter, occurring on the ventral surface of the body. Spiradenoma lesions are benign sudoriferous tumors, and have also been described as cystic epitheliomas of the sweat glands.
Primary cutaneous adenoid cystic carcinoma is a cutaneous condition characterized by a tumor that usually presents on the chest, scalp, or vulva of middle- to older-aged persons.
Pilomatricoma, is a benign skin tumor derived from the hair matrix. These neoplasms are relatively uncommon and typically occur on the scalp, face, and upper extremities. Clinically, pilomatricomas present as a subcutaneous nodule or cyst with unremarkable overlying epidermis that can range in size from 0.5-3.0 cm, but the largest reported case was 24 cm.
Proliferating epidermoid cysts are a cutaneous condition characterized by tumors that have deep invasion, and are associated with anaplasia and a high mitotic rate.
Proliferating trichilemmal cysts are a cutaneous condition characterized by proliferations of squamous cells forming scroll-like structures.
Pseudocyst of the auricle is a cutaneous condition characterized by a fluctuant, tense, noninflammatory swelling on the upper half of the ear.
SAHA syndrome, is a medical syndrome characterized by seborrhoea, acne, hirsutism and alopecia, and was first described in 1982. It is frequently associated with polycystic ovary syndrome, cystic mastitis, obesity, and infertility.
A Myxoid cyst is a cutaneous condition often characterized by nail plate depression and grooves.
Omphalomesenteric duct cysts are developmental defects relating to the closure of the omphalomesenteric duct. It usually disintegrates within six weeks of gestation, but remnants of the cyst can sometimes be found along the intestines or umbilicus. Any remnants can be removed via surgical means.
A keratocyst is a type of cutaneous cyst. They appear similar to epidermoid cysts; however, are not limited to a specified location on the body. Keratocyst are most often reported in persons with nevoid basal cell carcinoma syndrome.
Nasolacrimal duct cysts are a cutaneous condition that is a developmental defect present at birth.
Pigmentatio reticularis faciei et colli is a cutaneous condition characterized by a disturbance of human pigmentation.
Oculocerebrocutaneous syndrome is a condition characterized by orbital cysts, microphthalmia, porencephaly, agenesis of the corpus callosum, and facial skin tags.
Ciliated cyst of the vulva is a cutaneous condition characterized by a cyst of the vulva.
Microcystic lymphatic malformations are a cutaneous condition characterized by aggregations of ill-defined, abnormal, microscopic lymphatic channels.
Follicular hybrid cyst is a cutaneous condition characterized by a cyst composed of several adnexal components.
