SCC of the skin begins as a small nodule and as it enlarges the center becomes necrotic and sloughs and the nodule turns into an ulcer, and generally are developed from an actinic keratosis. Once keratinocytes begin to grow uncontrollably, they have the potential to become cancerous and produce cutaneous squamous-cell carcinoma. [22]
Preservation of lung volumes in the presence of increased interstitial markings is a radiographic hallmark of LAM that helps distinguish it from most other interstitial lung diseases, in which alveolar septal and interstitial expansion tend to increase the lung's elastic recoil properties and decreased lung volumes.
Persons with these findings, if they have a positive tuberculin skin test reaction, should be considered high-priority candidates for treatment of latent infection regardless of age. Conversely, calcified nodular lesions (calcified granuloma ) pose a very low risk for future progression to active tuberculosis.
Sarcoidosis (/ ˌ s ɑːr k ɔɪ ˈ d oʊ s ɪ s /; also known as Besnier–Boeck–Schaumann disease) is a disease involving abnormal collections of inflammatory cells that form lumps known as granulomata. [2] The disease usually begins in the lungs, skin, or lymph nodes. [2]
The scan also revealed abnormal increased activity at the gastro-esophageal junction (thick arrow). The final diagnosis was non-Hodgkin lymphoma at both sites. If there is an intermediate risk of malignancy, further imaging with positron emission tomography (PET scan) is appropriate (if available).
Desquamative interstitial pneumonia has a favourable prognosis and most patients improve with proper treatment. The mortality rate of DIP is between 6 and 28%. [22] The survival rate of DIP is estimated to be between 68% and 94%. Without treatment around 60% of patients get worse. Spontaneous recovery had also been reported. [16]

CT scan in a patient with usual interstitial pneumonia, showing interstitial thickening, architectural distortion, honeycombing and bronchiectasis.. In radiology, honeycombing or "honeycomb lung" is the radiological appearance seen with widespread pulmonary fibrosis [1] and is defined by the presence of small cystic spaces with irregularly thickened walls composed of fibrous tissue.
