Eccrine Acrospiroma is a medical term used to describe a benign tumor arising from the sweat gland ducts. The spelling of the word is derived from the combination of various Greek and Latin roots. The word 'eccrine' is from the Greek 'ekkrinon', meaning 'to secrete', while 'Acrospiroma' comes from the Greek 'akron', which translates to 'extremity,' and 'sphyrma', which means 'tumor.' The correct pronunciation of Eccrine Acrospiroma is /ˈɛkrɪn əˈkroʊspɪˌroʊmə/ with emphasis on the first syllables of both words.
Eccrine acrospiroma, also known as clear cell hidradenoma or nodular hidradenoma, is a rare benign tumor that arises from the eccrine sweat glands. It is typically found on the extremities, such as fingers, toes, and hands, but can also occur in other body regions including the head, trunk, and lower limbs.
Histologically, eccrine acrospiroma is characterized by well-demarcated nodules composed of small clear or pale cells surrounded by a fibrous capsule. These nodules may exhibit occasional cystic spaces filled with eosinophilic material. The clear cells are primarily derived from the secretory portion of the sweat gland and contain glycogen, giving them their characteristic appearance.
Clinically, eccrine acrospiroma typically presents as a solitary, slow-growing, painless nodule. While it is usually not associated with significant symptoms, there have been rare instances of pruritus or tenderness reported. The exact cause of eccrine acrospiroma is unknown, and it is thought to arise sporadically. It is more commonly seen in adults, particularly those in their 5th to 6th decade of life.
Diagnosis of eccrine acrospiroma usually requires a combination of clinical examination, histopathological analysis, and imaging techniques such as ultrasound or magnetic resonance imaging (MRI). Treatment usually involves surgical excision of the tumor, which is curative in most cases, although recurrence has been reported.
In summary, eccrine acrospiroma is a rare benign tumor originating from the sweat glands. Although it typically presents as a painless nodule, it should be evaluated and surgically removed to ensure accurate diagnosis and rule out any underlying malignancies.
The word "eccrine acrospiroma" is a medical term used to describe a benign tumor originating from the sweat glands. It derives from a combination of three terms:
1. "Eccrine" - The term "eccrine" comes from the Latin word "eccris", which means sweat. It refers to sweat glands that are present throughout the body and secrete sweat to regulate body temperature.
2. "Acro-" - The prefix "acro-" comes from the Greek word "akros", which means highest or extremity. In medical terminology, it is often used to refer to the ends of limbs or extremities.
3. "Spiroma" - The term "spiroma" is derived from the Greek word "spira", which means coil or coil-like structure. In medical terminology, it refers to a tumor arising from structures that have a spiral or twisted appearance.
