Pronunciation: [pɔːɹˈə͡ʊmə] (IPA) 
The spelling of the word "poroma" can be explained using IPA phonetic transcription. The first syllable is pronounced as "pɔːr", with a long vowel sound represented by the double "o". The second syllable is pronounced as "əʊmə", with the "o" representing a schwa sound and the "m" and "a" forming a syllable with an "o" sound. The word "poroma" is a medical term used to describe a type of benign tumor that originates from sweat glands.
Poroma is a specialized medical term that refers to a benign neoplasm arising from sweat glands, particularly from the superficial portion of the eccrine sweat duct. This type of tumor typically presents as a raised, firm, or sometimes softer, skin-colored or reddish papule or nodule. It can commonly be found on the head, neck, lower limbs, or extremities. Poromas usually measure between a few millimeters to a few centimeters in diameter.
Histologically, poromas are characterized by the proliferation of the sweat gland epithelial cells, forming numerous glandular structures that resemble the normal eccrine sweat ducts. The neoplastic cells often show features of differentiation towards these sweat gland ducts, with regular cells lining the luminal spaces.
While most poromas display a benign behavior, there are rare variants that can exhibit more aggressive characteristics, leading to deep invasion of surrounding tissues or metastasis to regional lymph nodes. In such cases, they are referred to as malignant poromas or porocarcinomas. Differential diagnoses for poromas typically include other benign or malignant cutaneous tumors arising from sweat glands, such as hidradenoma, spiradenoma, or eccrine carcinoma.
The identification of poromas is essential for accurate diagnosis, appropriate management, and potential surgical excision or treatment modalities, which may involve Mohs micrographic surgery or other wide local excision procedures. Regular follow-up and histopathological examination of these tumor types are necessary to assess potential malignancy or recurrence.

The word "poroma" is derived from multiple sources. Its root can be traced back to the ancient Greek word "poros" (πόρος), meaning "passage, pore, or duct". Additionally, "oma" is a suffix commonly used in medical terminology to denote a tumor or abnormal growth. Therefore, "poroma" refers to a tumor or benign neoplasm arising from the sweat glands or ducts.
