Overview
A skin nodule that is > or equal to 1 cm is referred to as a nodule. There are many differential diagnoses for nodules as they can be subcutaneous, intraepidermal, dermal or exophytic. To obtain the correct diagnosis it is important to observe the growth rate, color, symptoms and any underlying conditions that may have caused the nodules.

Causes by Organ System
Causes in Alphabetical Order
Differential Diagnosis
In alphabetical order. [1] [2]
- Dermatofibroma
- Dermal/subcutaneous neoplasms
- Epidermoid
- Epidermal inclusion cyst
- Ganglion cyst
- Hypertrophic scars
- Kaposi's sarcoma
- Lipoma
- Nodular melanomas
- Pilar cyst
- Pyogenic granuloma
- Xanthoma
Diagnosis
History and Symptoms
- Note the morphology of the nodule
- size changes
- tenderness
- History
- malignancies/ rheumatoid arthritis
- immunosupression
- family history of melanoma
Laboratory Findings
- Appropriate cultures should taken of suppurative lesions
Other Diagnostic Studies
- Biopsy to determine characteristics of nodule
- Shave
- Punch
- Excisional
Treatment
- Treatment includes excision whether for cosmetic or symptomatic reasons
- Epidermoid cysts:
- Lesions must calm down before excision
- Intralesional steroids
- It must be completely removed to avoid a recurrent lesion
