In the article entitled "Progressive Nodular Histiocytoma," published in the October Archives (1981;117:644-649), the legends for Fig 3 and 5 should have read as follows: "Fig 3.—Superficial papule showing lateral collarette and fibrohistiocytic infiltrate hugging epidermis. No grenz zone is evident (hematoxylin-eosin, original magnification ×30)." "Fig 5.—Deep nodule with grenz zone of normal dermis beneath epidermis. Overall pattern is more fibrous than that seen in Fig 4 and resembles a dermatofibroma (hematoxylin-eosin, original magnification ×30)."
