Bateman Pract. Synopsis Cutaneous Dis. 268 Molluscum. This form of tubercular disease is noticed rather as a singularity, which occasionally occurs, and of which a few instances are recorded, than as an object of medical treatment. 1817― Delineations of Cutaneous Dis. Explan. of Plate LXI, Molluscum contagiosum. This singular eruption had not been noticed by Dr. Willan, and was unknown to myself till after the publication of two editions of my Synopsis. 1818–20E.

XXXV. 225 The definition of Plenck could hardly be applied to any disease but Molluscum Contagiosum; the case recorded by Tilesius appears certainly to have been one of Molluscum Fibrosum. Ibid. 230 The patient was covered with the tumours of Molluscum, or, as he [sc. Virchow] prefers to term it, Fibroma Molluscum. 1899Allbutt's Syst. Med. VIII. 874 The molluscum tumours. 1932R. L.

XLVIII. 625 The microscopic architecture bears a resemblance to molluscum contagiosum, and it is possible that some of the recorded cases of giant molluscum contagiosum are examples of this tumour. We suggest the name ‘molluscum sebaceum’ as a convenient label. 1950Molluscum sebaceum [see kerato-acanthoma s.v. kerato-]. 1960J. Marshall Dis. Skin xxvi. 684 Molluscum sebaceum presents as a solitary lesion usually on the centre face, sometimes..elsewhere. 1961D. M. Pillsbury et al. Man. Cutaneous Med. ix. 205 Molluscum is of no more than cosmetic importance, except when the conjunctivae are involved. 1967H. Montgomery Dermatopathology II. xxxiv. 1036/2 Cutaneous tags or papillomas have been given many different names in the older literature, including acrochordon, fibroma molluscum, molluscum fibrosum, and soft warts. 1970Passmore & Robson Compan. Med. Stud. II. xviii, 116/2 Cowpox may develop after contact with infected animals... In contrast, molluscum contagiosum is contracted only from human cases.
b. A soft nodule characteristic of molluscum.
1841Edin. Med. & Surg. Jrnl. LVI. 216 In the 2d and 3d Figures are represented the free and attached surfaces of a tubercle, consisting of three mollusca, each with its proper aperture. 1890J. L. Milton On Path. & Treatm. Dis. Skin (ed. 3) ix. 449 A boy, twenty-two months old, was brought to St. John's Hospital with several molluscum spots on the left side of the face and neck... His mother, who had suckled him, had now a molluscum on her breast. 1960J. Marshall Dis. Skin xv. 336 When they appear the papules [of molluscum contagiosum] are 1 to 2 mm. in diameter and the fully developed lesions are usually 5 to 10 mm.; but much larger ‘giant mollusca’ are sometimes seen.
c. attrib., as molluscum tumour; molluscum body, † corpuscle, one of the characteristic ovoid bodies that are found in the core of the nodules of molluscum contagiosum and are thought to be degenerate epidermal cells; also, a cytoplasmic inclusion in a cell that is in the early stages of degeneration.
1892Edin. Med. Jrnl. XXXVIII. 283 The so-called molluscum bodies..are not independent animal organisms. 1937E. H. Molesworth Introd. Dermatol. vii. 228 The so-called molluscum bodies are degenerate and deformed cells contained in the core of the lesion. They are not the infective agents. 1966Wright & Symmers Systemic Path. II. xxxix. 1571/2 The epidermal cells that are infected by the virus [of molluscum contagiosum] undergo premature keratinization and form the so-called molluscum bodies, which contain the virus inclusions. 1974Passmore & Robson Compan. Med. Stud. III. ii. xxxi. 58/1 Cytoplasmic inclusions (molluscum bodies) form in the cells of the stratum spinosum.
1886C. H. Fagge Princ. & Pract. Med. II. 688 The white material seems to be made up almost entirely of characteristic oval transparent bodies..without a nucleus... These have been described as molluscum corpuscles.
