Summary
Nodular hidradenomas are rare benign sweat gland tumors. A case report details a 22-year-old male with an atypical scalp lesion exhibiting features of hidradenoma, highlighting diagnostic considerations.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Eccrine acrospiromas, or hidradenomas, are uncommon benign neoplasms originating from eccrine sweat glands.
- Their etiology and prevalence remain poorly understood, with potential spontaneous or traumatic origins.
Observation:
- A 22-year-old male presented with a three-year history of a painless, progressively enlarging, and bleeding scalp lesion.
- Clinical examination revealed a solitary, pedunculated, red scalp mass measuring 2 x 2 x 3 cm.
Findings:
- Histopathological examination confirmed an adnexal tumor consistent with nodular hidradenoma.
- Atypical features included involvement of deep/peripheral margins, a mitotic rate up to 3/10 HPF, and focal necrosis.
Implications:
- This case underscores the importance of considering hidradenoma in the differential diagnosis of scalp neoplasms.
- Atypical features necessitate careful histopathological evaluation to distinguish from malignant counterparts like hidradenocarcinoma.

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:18Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
